MkVII Modular Shoulder System

A fully customizable shoulder armor system for any occasion.

My original attempt at building the MkVII shoulder armor with fully interchangeable plates was after the Halo Infinite Beta. With limited time and resources, I was happy with the original product. However, since the full release there were a number of fixes and upgrades I added to the armor, so I decided to rerelease the files and start to expand the array of shoulder plates available. Going forward, I hope this is the starting building block to a fully customizable MkVII armor set.


Major Features

Base Arm Attachment

This set features a 3-part main arm piece that all shoulder pieces bolt into. It is comprised of a main ring/tricep piece, a front bicep plate, and a side plate that features a middle bar that all shoulder pieces slide on top of, as well as two printable bolts that secures the shoulder plate.

All three pieces fit together with 3D printable bolts that have smoothed heads to ensure the inside of the armor is completely smooth.

The inside of the main arm armor is modeled to easily conform to someone's arm/padding. All three pieces features a channel for a strap to fit through in order to secure the armor to the wearers arm. Additionally there are three separate outlet channels for the strap in order to fit several sizes of arms.

All shoulder plates fit on either the left or right arm.

One addition that was made to the upgraded version of this armor, is that there is now a vertical channel to accommodate a strap that will hold the shoulder armor up on you shoulder. This can be done by tying the two shoulder armors together and having that strap rest on the back of the neck. I found this was an extremely secure way to ensure the shoulder armor never slipped past where the user wanted it. I prototyped this technique with my ODST armor set (coming very soon ;)...)

Included Attachments

For now there are 4 included shoulder attachments. These are the four shoulder plates that appeared in the beta. When I do a full MkVII release, all shoulder plates will be included but for now additional novelty plates like the HIGHCOM Sentinel, can be purchased seperately.


The Agathius Armor features a multi-part design to ensure that sanding/painting/printing different pieces is made much easier. The Agathius shoulder is two main pieces fit together with two printable bolts. Agathius features an insert feature and bolt features to attach to the base arm armor.


The ALAIR model is a simple one piece design w/ included insert and bolt features.


The VIATOR Plate is the largest plate in the set and features a multi-part design in order to ensure you can easily print/sand/paint the different accents. Contains all the necessary inserts to secure to the base arm armor.


VITUS is another single part design with all necessary inserts and bolt threadings required to secure to the base arm armor.



If you have any MkVII builds using my models, I would love to see them! Email me at and I can offer you discount codes for finished photos of your props!

If you are looking to create you own models like this one feel free to checkout all of my tutorials on 3D modeling and prop making techniques.

If you are looking to purchase the model so that you can print your own you can find it in the store.

Lastly, make sure to check back in every once in a while to see what I've been working on

Thank you for your time
