Prof's Halo 3 Marine - Rookie Build

Hello all, new blood here, y'all can call me Prof or Tyler. Got dragged into all this by a friend, and ended up doing the whole thing backwards. Went to a con, then went to a shoot, then joined the forums, and finally started a build. Halo 3 was a defining halo for me, even above and beyond Reach, and I had a hell of a time running around with my Marine buddies back when. Figured it'd be a fitting tribute for me to join them, so here we are! I'll be logging down what I do here, once I've got enough to show for a thing, anyway.

This will be my first ever cosplay build, and I'll be going at it with Fusion 360, a 3d printer, no artistic talent whatever, and a determination to make and print my own files. Most importantly, a fellow 405th member is going to provide some assistance with fabric work, in return for some prints and stuff. Its gonna be a fun ride! To get a feel for Fusion and autocad in general, I went ahead and started modelling a Biofoam canister. Figured it'd be a good starter prop for any halo build, and a nice learning platform.

Its still work in progress and I'll probably add a few surface details, but in keeping with wanting to have a bit of spin on things, I decided to answer the question of "How does the nozzle not just flop around all the time" with a pull pin - with a pivot pin as well, so hopefully it can be a useful prop for shoots and such. Plus its just fun to make things move.

As for the marine proper, I'm apparently making the circumstances of my introduction a tradition, by starting from the outside and going in. I'm working on losing a bit of weight to better fit what I have envisioned, but my head, hands and feet ain't changing size anytime soon. So I went out, and got some combat boots and gloves, and started sketching ideas for the Helmet.

View attachment 321844View attachment 321843
The boots are more or less perfect. The gloves don't quite match the references I've seen, but they fit flawlessly and I'll take a perfect fit and no glove chafing over a slightly more accurate back rubber any day of the week. Tried to get a BDU as well, but they didn't have anything in the right shades for a Marine, even with some leniency. Gonna check back in a few weeks, otherwise might just order online. Not like there's a shortage of other things to make.

Over the next couple weeks I'll be drafting up the ankle and shin plating, and a first pass on the helmet size plus some padding buffer space. But before I can get into that, I've already been asked to help make a new print for a Reach Magnum - I have even been provided a broken print. Don't know who's design this is, but whoever it is, you did good, and I've seen it around a lot, promise I won't just lift your measurements. The best use of it so far is to help me understand how thick Xmm is actually in the hand, its really hard to judge scale in program. You lose sense of how big a millimeter is when its just on a screen at arbitrary zoom.

View attachment 321842
I'll be making the Halo 3 Magnum alongside it, since they're pretty similar, and the general component and operating technique for the one should be useable for the other. I'm aiming for detachable magazines and moveable slides, but ambition and reality don't always agree, and I'm pretty green to this. An assault rifle is on the plan as well, but not on my active list of works.

My goal is to have all this put together before April of 2023, when my next local convention is. Work and life permitting, it should be doable, but I'd love to hear any of your guys input, thoughts, or advice!
yo so i’m kinda lazy and i’m wondering where i can buy

This sort of question might be best asked in its own thread, as it doesn't really pertain to this specific build.

There aren't too many kits out there that you can just buy and wear. Most of the time that sort of thing is done on a commission basis. However, there is a reputable ODST kit seller known as Sean Bradley that sells all of the armour pieces needed to make an ODST kit. You'll still have to do a lot of work sanding, trimming, prepping, painting, rigging, etc. but it will take care of a lot of the time-consuming process of crafting the physical armour pieces.

As for the assault rifle, you may be able to find something on etsy, but for the most part again that's often done on a commission basis and takes a lot of time. The nerf AR is fairly accurate and very durable. Many members have repainted their nerf AR's with lots of success.
 
thank u very much. idk why but when i tried to post a thread about this it wouldn’t let me, saying that the title wasn’t valid or something so i just did this. thank u very much however!
 
Ok, this was a bit of a wild week for me! Right to the meat of it, the printer worked an absolute dream, and got everything out with only one minor failure - Edge of an arm went spaghetti on me, but it was so quick and easy to just reprint it that I went for that rather than trying to fix it up. And despite waiting a week for the printer to arrive, this job got done before the old printer woulda managed it by a couple days.

The print quality was amazing, and I'm extremely happy with how everything came out. Was even able to sleep through the printer running, which is saying something in a studio apartment.

it also barely warped or deformed at all, to the point that this back seam was able to be straight up press fit, which was a big contrast to the helmet where I had to use clamps to bend things a bit back into shape when I was gluing the two halves I had.
halfback.jpg


Of course, I did glue everything - Just hit it with Gorilla glue, seems to have worked fine. Picked up some cheap clamps from Canadian tire to help with applying pressure, which worked out pretty well on most of it.
chestassembled.jpg
backassembled.jpg


Even worked to clamp in the magnets into the lower arms, real nice fit there, seam works perfectly and they slip over each other to interface well.
magnetsin.jpg


However, those lower arms were also my bane - I did not give much consideration to the need for clamping forces when I designed them, and frankly the alignment pins were too shallow to do much more than vaguely guide me, they didn't resist pivoting at all. Lesson learned, and in the meantime I had to get exceedingly creative with how to position the parts to apply pressure, and use extra clamps and filaments I bought to orient stuff. - The upper clamp in the first pic is only there to provide another edge as a pseudo flat surface to allow those boxes to balance.

jankylowerarms.jpg
morejankylowerarms.jpg


But, once it all came together, its past my wildest expectations for fit. Despite only being retained by pressure and the lower magnets, everything rests in such a way that I can actually wear it, assembled and unassisted, without the upper straps that even hold the chest in place - At least for long enough to take a photo, the magnets and press-fit do slowly slip.
wearablenostrapsmygod.jpg


Its actually fairly comfortable and not too restrictive to my movements - my arms can move about fine, and I can reach around, lean etc without interference. I'm a bit worried the armored collar might be too high and interfere with the helmet, but I don't have it here to check. Worst case scenario, I fall back onto the hat I made, as planned.

I've got a lot of sanding, finishing, painting and priming work to do, but at least its an easy enough thing to paint, and with the sheer smoothness of the prints, I shouldn't need to do much finishing work at all. Also gotta sink the threaded inserts for the screws to hold the straps in, just need to get my soldering iron back from a friend. If anyone has any lessons learned or advice to impart about sewing/gluing/working with nylon strapping, I'd love to hear it! I think I can get this done before the Calgary Expo here, but its gonna be a crunch.

If there is an update next week, it'll be a small one, probably just strapping it and initial sanding, because I'm losing the next four days to compete in Ludum Dare - As much as I love video game cosplay, making video games still comes first :p.

One tip is to try and avoid gluing parachute clips directly to the armour. It's much more secure to put a strap through the clip, and glue the strap to the armour.

For thick fabrics like nylon strapping, you'll want to increase the tension on your sewing machine to lift the lower thread up to the middle of your fabric. I don't have an industrial or semi-industrial machine, but I did add a walking foot which is helpful for the thick straps. I forget which needle I used (as I don't have my machine in front of me as I type this), but just ask the person at your local sewing shop and they'll give you some good suggestion on what needle to use. Whichever needle you end up using, make sure it's new and sharp. If your machine cannot accept a larger thread (most household machines cannot) then regular thread will work just fine. You can use a zig-zag or straight stitch. Make sure you go slow! Those older pedals have less control, so be careful! Straps are quite narrow, and you'll have to make lots of 90 degree turns. You don't want to go off the edge of the strap, so there's no need to rush here.

Make sure you are not using anything with adhesive. If you try to sew through anything that has a stick side to it, it will most certainly cause you a world of headache.

Now I'm no expert. This is just what I've learned from the little bit of sewing I've done. If anyone has any extra advice I'd love to hear it as well! Best of luck on your strapping man!
 
Alright, time for an absolute Beast of an update. Only finished my con crunch a few hours ago, and the cons tomorrow, but I got what I wanted done, at least. Unfortunately, I didn't take a lot of photos in some steps, so there's gonna be some gaps followed by "and then here's the thing".

Picking right up from where we left off, I had armor printed, and it was time to sand. However, the weather was not being cooperative. Sanding outside wasn't an option, and my indoor options were limited - I live in a studio apartment, and the main space is carpet. All I had was the entrance hall. So, I went to Canadian Tire, and bought myself a chair...

Ominous Sanding Station.jpg

And ended up with probably the most ominous sanding station you could imagine. It was a bit awkward working everything over my knee, but an apron helped a lot, and then cleanup on the tiles was a breeze. By the time I had to take it outside to sand the spot putty application later on, things were warmer. It was around this time that I took the pieces and filled the holes I included in the models with the threaded brass inserts, which worked out great. I unfortunately don't have photo's of the sanded items so far as I can tell, except for one - Because the back plate had a glue failure during my work, and one of the legs broke off! Scraped the Gorilla glue off, and applied some E6000 I had gotten since the first glue round, and sent it right back into janky clamp land, with an even more aggressive clamping pressure. Random filament boxes come out to save the day, once again.

repairwork.jpg

The good news is this repair has held, and I haven't had any major issues - the E6000 didn't seem to like the primer in a spot, but I suspect its because I didn't let it dry a full 72 and it interacted weirdly. Its on the inner surface though, so no harm done. Speaking of, I had to paint this whole mess. By this point the worst of the cold weather had broken for good, but Canada be as Canada do, and it was windy. Luckily, the 3d printer could help with this too! Not by printing anything useful, of course, but you see, the printer came in a really big box, that I still had. So when I was out buying the sanding throne, I also got a tiny plastic table, and a few firebricks for weight, and set up my Advanced Solution Systems painting station, by putting the bricks in the box and the box on the table. To my surprise, it worked!

advanced painting solutions.jpg

Also pictured, the boot plates going through - I had to reprint them AGAIN because I realized I had the sizing of the back loops wrong to fit the straps I got, but that only took a pittance of time, and I realized well before I sanded and finished anything. I don't have any good photos of priming in progress, but I managed to avoid any terrible runs and did manage to apply primer all over, even when I could only paint from one direction. Just took more coats and turning.

Out the other side, however, I had some decent pieces.

primedchest.jpg

The filler/sanding loop was getting frustrating and I was running a bit outta time, so I ended up deciding that complete is better than perfect, and just went for it with a few imperfections. And imperfections abound - priming outside, even with the box to protect from the worst of the wind, seemed to have collected a lotta faint debris. Nothing terrible aside from a few annoying hairs, but irksome. Good news is the filler did a great job of all but masking the remaining layer lines.

finishbutweirdedge.jpg

So, while it went in for painting, I did some painting of my own. Specifically, I had some details for the magnum to finish, so busted out the brushes and citadels. The only part that didn't cooperate was the yellow - I feel like I had to lay it on so thick for it to not be translucent, that some details like the sight post just came out blobby feeling. Couldn't get in there well either. Still, not a bad first try.

fullyoperationalbattlemagnum.jpg

But that still left me with time to use while my main layer colors went down on the armor, and sewing that needed to be done. I consider myself as not knowing how to sew, but took a crack at things anyway. First up, the weird brown belly plate thing. I don't have in-process photos, I just went for it apparently, and came out with these middling pieces.

badatsewing.jpg

They got upholstery foam for structure, and zippers to let me get the foam out - one of which I somehow managed to sew onto the wrong side - Again, I'm not a smart man. Trying to figure out how to keep them in place, I just thought I'd let the belt do it with a band between them.

almost worked.jpg

It didn't really work out, top plate would flop down. This all has to go back to the drawing board, so I didn't bother sewing in the rest of the details. Can't win them all, I suppose. But when this finished, so did the flats for the chestplate - And I was worried, because it was looking paler than I'd hoped.

painted flats.jpg

So while the back plate went in for its flats, I got to work weathering it, and kind of fucked up. I don't have any photos because I wasn't super happy with it and didn't want to show anyone, but I ended up deciding "I can darken it while applying the wash" and went a bit heavy on that. I also did some silver edge scratching, since I didn't have a real silver undercoat or anything. By the time I was done with the chestplate, the backplate had its flats and came in for the same treatment, including the heavy wash - it was there I had actual notable issues that persist, blobs and streaks of shame you'll see later. But, I didn't let that deter me - I needed something to work on before sending the armor back out to be sealed, so I decided to get the straps going. Somewhere in this process, I'd modeled and printed out real quick the blocky shoulder straps the marine armor uses, and had already primed and hand painted them - I genuinely can't recall exactly when, its been a fuzzy two weeks. But, started measuring out and positioning the straps and hardware, and using my attachment plan - melting holes in the straps with my iron.

weirdmarineshoulders.jpg
straps.jpg
butitworks.jpg
usingthethreadedinserts.jpg


Took a bunch of pins, some time, a sacrificial empty filament box to burn through, and one minor layer of iron induced skin removal, and the results? Pretty good!
fullyfunctionalstraps.jpg
firstarmorfit.jpg


And that first fit emboldened me. See, the marine has that black undershirt, with two distinct lines down it, and the half-sleeves with the straps. Weird stuff. But I was feeling confident enough to try it. And to be fair, that confidence was a trap, but one I didn't leave empty handed from. So while the armor went out to seal, I did the thing. I don't have photos along the way, but I do have another bad selfie, but in the 'full softs' as I called it. Also pistol because why not.
firstsoftsfit.jpg


Also pictured, the haircut to make me look like someone who should be in camo and a patrol cap, rather than a crazy man as I did earlier with the cap. You can't really make out the lines I sewed in the photo, but they're there, and visible in person. I think. Either way, this is officially placeholder. The sleeves are really bad, the shoulders as a whole are far too wide, but I learned a lot of what not to do for next time. At the least, this'll work until I make a replacement. But any disappointment I might have had in the shirt was dismissed entirely when I brought the chest in from being sealed - Because I was completely ignorant to the fact that the sealer would darken everything under it! Not by an incredible amount, but by enough for me to be much happier with the look.
sealedndealed.jpg


This is also when I removed the masking tape from the area intended for the velcro, and glued that down over the raw plastic for better adhesion. I didn't end up using screws there, but if the E6000 doesn't turn out to be enough in the future, they'll still be there. I didn't take any photos of sticking the velcro on, but you'll see it later. So while the back plate was sealing, I started strapping the boots up as well, buckles and slides to make them adjustable enough to ensure a good fit - hopefully. Another "I'll show it later" piece. Dayjob kept me busy for most of the rest of the sealing period, but came right out of it to add a detail I nearly forgot, the fabric under the straps for the shoulders. Hit it with some quick sewing, and eyelets to allow the screws to pass through without the fabric falling apart. Three sides of it are beautifully sealed, and one side is garbage, but I'm hiding that under the buckles so maybe nobody will notice :p

But, that takes us to the end of the documented journey! Here's the final hards lineup!
thelineup.jpg


From here you can see the velcro on the chest, the D-Rings on the bottom of the marine straps in case I ever want to hang a bag or something off them, and the boots all buckled up. Here's some 'glamor' shots if you want to see my bad filler, sanding and wash jobs. The splotches around the rivet holes in the backplate are particularly bad and painful.
badfillerwork.jpg
thechest.jpg


My favorite part by far is also the part I was most worried about, the side joint for the front and back. As a refresher, they slide over eachother, and lock in place with a combination of pressure/friction fit, and magnets. And these lock together flawlessly, I'm so happy.
magnetic joint.jpg
perfect fit.jpg


The bootplates also interface pretty well, they're actually retained firmly enough that moving them into position is almost as hard as moving them out of position, intentionally or otherwise. The buckles come around the right rear side, just as in the halo 3 models, and use slides to adjust tightness, or to remove the strap if needed in the future.
wearingbootplates.jpg
buckledsides.jpg


Which takes us right to the end, con ready, for now at least! You'll have to excuse the terrible photos, between the gloves and being excited, my already terrible selfie skills achieved an entirely new legendary level of failure. Also pictured, a close up of the collar, just to show that it doesn't actually poke or jab the head at all.

sidedoesnthurtalsohair.jpg


And that's that! The big missing piece, obviously, is the helmet. Simply put, didn't have time, triaged it out. Making due with the officers cap for now, anyway. I'm sure I'll have better photos of it all from this weekends Calgary Expo!

Y'know, writing this and looking back, that is a lot of stuff I did for con crunch. Kind of wild what you can do when you put your mind to it. And don't mind some of the floating threads in the pictures, I've gotta do a quick scissors clean up but just kept having more to do first. Other than that, I'd love to hear what y'all have to say about it, super excited to have reached this point!
 
WOW a beast of an update indeed!

I love that sanding station! XD Very ominous indeed lol
The painting station is good too! Gotta work with what you got
The only part that didn't cooperate was the yellow - I feel like I had to lay it on so thick for it to not be translucent
Yellow is particularly difficult. Sometimes, I have to lay down a new layer of white primer where I want the yellow to go because it will want to be do translucent.
This all has to go back to the drawing board, so I didn't bother sewing in the rest of the details.
Do you think you could use Velcro or snaps to hold this part up?
Either way, this is officially placeholder. The sleeves are really bad, the shoulders as a whole are far too wide, but I learned a lot of what not to do for next time. At the least, this'll work until I make a replacement.
Hey this is what making stuff is all about! Trying stuff, sometimes it doesn't work, then you'll know what to do for next time. Looks just fine as your placeholder :D
But, that takes us to the end of the documented journey! Here's the final hards lineup!
Armour pieces look great! Photos are good as well! Glad to see the colour came back better than you anticipated. Don't be too hard on yourself, nobody makes a perfect suit or takes a perfect picture on their first try. You've learned a lot from making this suit and you'll be able to take those skills and make a fantastic helmet to top off your suit. Suit looks great! Congrats on getting it all con-ready
