This will be a little tedious at first. Give me a little bit, I'll look for an easy way first but if that fails, I'll have to go the longer way to try and make it work.

Thank you so much!! just worry about the half. Ill duplicate and mirror it in 3D builder later. Also, if possible, could you explain what you did? I would like to know for future use.

Sorry but this is the best I can do with the file at the moment and it took about 3 hours to get here. I could either give it a thin wall or a really thick wall. As for what I did,
1) I started with the .stl file you provided and put it in Edit Mode in blender,
2) deleted half the Model
3) deleted inside polygons that were extra in my opinion
4) ran it through an add on I use in Blender called "Mesh: 3D Print Toolbox" which checks all the potential print problems
5) selected all the intersect polygons
6) hit CTRL F
7) Hit Intersect: Knife
8) on the left side where you see the options for intersect, Under source, select "Self Intersect"
9) give the model a mirror to complete it
10) smooth out all the spots that need smoothing
11) send the model to Makeprintable.com - They will close up all the holes and fix a bunch of problems, but it is limited.
12) bring the model back in
13) add a "solidify" to the model to increase the internal wall thickness . In this case, that didn't work (resulted in thin wall with imperfections on the outside) so I made a copy of the model in Blender, scaled it down slightly smaller, reversed all the normals, joined the models together, bridged the gaps around the neck

I uploaded a zip with my blender file that has several models inside. One has the thick wall, one has no wall. I also included the thick wall in one piece in case you want to resize it. Also, I cut up the thick walled helmet for a print bed.

That model was tough to salvage for me. I'm still new at blender but boy, what a pain. Hope the wall thickness isn't a dealbreaker for you. Otherwise, you can use the model that has no wall thickness to get to the size you want.

again, thanks a lot. I did a little bit of "carving out" in 3D builder to make a little more room on the inside, but I think it will do. If it doesn't work printing, their is always the D1 version Crimmson made.

Your carving notion reminded me of the smooth function on blender sculpt mode. I used it to smooth the internal mask. This one has a smaller wall than then last one I sent you. According to simplify3D, it shows that it is good to print.

Holy cow! That made a huge difference, it did what I basically did but like 10 times better! The bumps on the inside are completely gone! By any chance, could I get the blender file too? just in case I want to make any changes? My main concern is that bottom lip making issues with actually putting it on.

Cool! Now I just need to figure out the best way of dealing with all the holes it has...

EDIT: I didn't realize the model had grown in poly count, gee wiz. To be honest, how big of an issue could the bottom lip be with getting the helmet on?

I would either cut off the bottom lip or have the back bottom half be removable with super magnets or even stretch fabric. I didn't know the helmet needed holes. I'll make some the size of LED's and see how they pan out. Should look pretty cool once installed.

Note, in blender, just add cylinders until you get it where you want, then use a mirror to even out both sides, Finally, use the boolean modifier to cut the holes.

I really can't thank you enough. You have really helped make this possible. I have been panicking a little due to a math mid term for college and seeing that image really made me happy so thanks!

Would anyone be willing to either unfold the Halo 5 Helljumper (or Edward Buck armor) from the Armory for foam use, or know if the files in the Armory can be used on a 3d printer as-is? I'd love to build my armor myself, but if I can use the .obj files with a printer then that might be easier (plus, courtesy of the kindness of my sister, I actually have some limited access to a printer). My Mac is malfunctioning right now, so even if I had the programs needed to manipulate a pep file (and the knowledge of how to work with pep files) I don't know if it would behave long enough for me to unfold the pieces.

If it helps, I already did his 3D printable helmet from a pepakura file a while back. - Halo 5 - Mjolnir - Gen2 - Helljumper - Buck - Helmet by moesizzlac.

That helps a lot! The helmet is the most intimidating part of the armor for me, followed closely by the chest piece, so if I can get my sister to help me 3d print it that would make me a very happy man. Still leaves the rest of the armor, though; I tried a little freehand yesterday and successfully wasted half a sheet of puzzle mat, so I don't really want to try that again

Just want to make sure... Are you ok with me putting the file in a future build thread? Ill say you made it, but then it would be easier to find and I plan on asking Crimmson if I can put a modified version of his D1 model their as well.

It's no big deal. I put the stl on thingiverse so that others can find it easily as well. Destiny Skullfort Helmet - With and without holes. by moesizzlac.

Now will you stop posting and concentrate on your math midterms already?

This! What's your length, width and height of your head. Circumference would help
as well but I can make due with the previous 3 dimensions.
Circumference roughly 37"
Roughly 6" wide ear-to-ear
Roughly 10" tall crown-to-chin
Roughly 10" long nosetip-to-back

Any thing I upload here I always state use it as you see fit. Credit is not needed with me, but thank you if you do. It wasn't mine to begin with I just prepped it for pepakura. Hope it it helps you and good luck with all your builds

I just downloaded the model from thingiverse into Blender and scaling to about 7.396 (about 739.6%) will get you to a fit that looks like the below give or take:

Untitled.jpg


That is based on your dimensions of a 10 x 6 x 10 head not including the neck of course.

The overall helmet would be about 276.783mm x 306.457mm x 273.952mm (10.89" x 12.06" x 10.78")

Thanks! Is that something I can set in printer settings before starting the print?

Also, does anyone know of any unfolded Buck armor files around anywhere that I could use to pattern for foam for the rest of the armor? I don't have access to any pep programs

It's a step in your slicer program before exporting gcode to your printer. Unless you have a large format machine (400mm x 400mm bed) you'll likely need to split the file up into multiple more manageable pieces before considering printing.

I'm looking for a .stl (or other 3D file type) file for some Halo Mk. IV Spartan Armor (or any) gloves so I can 3D print them.

I'm mostly looking for the finger joint thingys that look like the picture linked in my post that I can hot glue onto some gloves so my hands don't look bare.

If it helps, I have U.S. Large sized hands

Many thanks!
