It'd be easier to help you if we all knew what steps you've taken to get here, such as how you scaled your pieces, if you've got accurate measurements, etc.

Also, we don't discuss airsoft on the forums due to liability and safety of our members :D

 
Aww man... cyne beat me to it

You'll want to get Armorsmith to make a proper avatar then you can scale the armor to that. Or have someone with it build you an avatar and do your scaling.

My "New Armorer FAQ" thread:
SgtSaint's FAQ post
<spoiler> I commonly recommend
1 - starting with a less unforgiving build as your first armor, then work up to one's like this with tighter and tighter tolerances after you've leveled up your scaling skills.
2 - Start at the feet and work up, helmet last after you've gained skills at scaling and printing.</spoiler>

My 1st Spartan build (Not awesome)
First {Halo} build - Spartan (TV series)

My 2nd Spartan build
Build 2 - MK-VI gen-3. With some silver timeline influence

My 3rd Spartan build (just realized I need to finish this with more details)
MK-VI Silver team season 2 [2024 build]

My ODST Build

Ok the problem is though the width is perfect but the length is to big and if I size it down at all it will be to small
 
Also I can’t buy armor smith
Why not? Is it blocked in your country or something? Or are you on a Macintosh instead of Windows?


and nobody I know has it
You can pay to have someone do it

Ok the problem is though the width is perfect but the length is to big and if I size it down at all it will be to small

You need to learn how to size disproportionately (X = 100, Y =86, Z = 92). Its how every part of my armor is: Legs shorter but thicker... helmet wider but same depth... forearms more "Popeye at the muscle" and normal at the wrist... etc. etc.
as well as do custom distorting. I'm big in the chest/ribs and always have to do a parallelogram type distortion for my ribs (see ODST below).

This is a big reason why in my FAQ that I push doing a less exacting armor first and work up to more technical suits that require greater scaling skills and tools. Basically "If you're going to (re)print 3 suits anyway, you might as well have 3 you can wear instead of 1 you can wear and 2 that are piles of waste on the shop floor."

Plenty of people have armoursmith but still can’t scale properly.

Theres is other free alternatives that can help to assemble something in 3D space and grab measurements. It’s a bit harder to get now but I still prefer windows 3D builder as a free alternative.

Ultimately it’s a learning curve but many software packages even slicer can have point to point measurement tools which go a lot better than armoursmith in my opinion, just compare spacing of openings on the model and reference your body. Try to keep armour proportional as a whole while allowing them to fit individually, it’s a balance you have to get with some trial and error.
 
I agree there are other tools... free tools. No dispute there.
I did my first Spartan with Windows 3d Builder. Planned the colors out in Photoshop.

scheme I was going for:

A couple things killed me with that plan
1 - It was the very old version of the MK-VIgen3 and they were not good files. G.A. as since totally remastered that suit and provided free updates to all previous buyers - So great customer support there.
2 - Even though I had a good body avatar in 3d builder it doesn't articulate and I didn't see collisions for things like sittings, kneeling, walking stairs, posing.
3 - lack of free-form deformation makes it impossible to get anything more customized than simplistic XYZ scaling.

Can 3d builder be helpful? Sure. And its free. But...
> Plenty of people have armoursmith but still can’t scale properly.
I'm not sure that's an issue with Armorsmith so much as inexperience at all the skills: Scaling software, building and experience in WEARING to know what you'd do differently the next time. I know it was in my case for my first Spartan. Which is why I now suggest starting with less tolerance-demanding armors so people can build up scaling expertise on a Mando, Aliens Colonial Marine, ODST then a Spartan.

At the very least, if there was one bit of advice I could give someone on their first Spartan: Give more joint room than you think. There's a desire to cover every square mm of your body in armor because that feels tactically right - but then you can bend anywhere.
