My Project MJOLNIR: Mk. VII armor + rubber undersuit

[armoryofalbus]

I'm glad I stumbled across your thread. I'm remaking my Mrk V with Titlewavedesign files, and I bought InstinctCreative3D undersuit files but never got around to using them.

Nice, yeah the two can pair together really nicely

Hello 405th! Here’s my first post on here: a build thread documenting my build of Mk. VII MJOLNIR Armor. My build includes a rubber undersuit I made using Smooth On’s Dragon Skin 10 Fast. A lot of the pics in this thread come from my Instagram stories, where I have posted this build throughout months of sporadic work on it. Feel free to check that at “armoryofalbus” on insta

This past year I started reading the OG Halo books, and that inspired me to make my Spartan a solemn, no-nonsense green boi. (Secretly I just wanted to get called Master Chief at all the cons…NOT lol). I still probably love the Mk V B the most, but the Mk VII has some really cool elements to it and that’s what I opted for. Still drawing inspiration from Reach, my favorite game, I've gone for a Commando shoulder and Emile's small one (not sure its name atm) as my main shoulder parts. However I've also printed 4 other shoulders and plan to make them interchangeable (couldn't decide, LOL).

I completed the suit in May 2025. I began printing things near the end of December 2023. I took my time with this project and did not rush to get things done. No deadline really. So it was very satisfying to finally see it come together. Read on to see some of the steps I took to do this.

I wear a paint-ball vest with some added foam pieces. It gets pretty sweaty.

I’ve only worn it for 2 hours max so far, and the biggest thing for me was the weight, less the sweat. I’m hoping to wear this at Fan X in Utah next week so we will see how that goes.

Your armor looks fantastic – especially the undersuit, it’s really awesome!


Now, my eagle eyes did spot something – I think your boot plate might be flipped. At least on the tongue piece, the files in the forum show the rounded, wider side facing down.

Thanks! Yep you’re right, I made a mistake while gluing the straps of that part on one of the boots and didn’t have time to correct it before this photoshoot lol. I always overengineer stuff and I didn’t have time to undo my glue + resin job. But good eye

That undersuit is stunning. Incredible work! Love the build thread. I need to step my undersuit up hard!
