16th Century Plate Armor Cuirass Breastplate and Backplate 3D print model

A historically accurate 3D printed cuirass, with breastplate, backplate, arm gussets, and an optional lance rest.

I set out on a journey to design the best wearable 3D printed armor I could come up with, after being disappointed with the historical accuracy of what was available online.

I wanted something historically accurate to real mid-16th century antique armor from renaissance Europe. I believe that, apart from the material, plate thickness, fastener type, and the fact these are printed; these files are a decent attempt at accuracy and offers the same aesthetic and range of motion a real 16th cuirass would offer.

I am very happy to share this labor of love with you, and I hope that the included guide can help you make your own printed “antique” piece, something that will look great in your next project.

=> This is a set of .stl files I designed to fit a 220x220mm print bed. They are easy to print and assemble using minimal hardware.

=> I created a pdf assembly guide to take you from the basic “print and wear” assembly all the way to a fully painted and weathered piece, like in the photos.

=> I recommend printing with PETG or PETG-CF for durability, ease of sanding, and UV resistance.

=> All the fasteners, tools and hardware necessary for an accurate replica are listed in the guide. This model makes use of m5 chicago screws, 6x6mm and 8x8mm cap rivets, superglue, and fake leather strips. I recommend sourcing the hardware suggested in the guide.

=> Enclosed are the instructions on how to set up and scale the files for your own build. The instructions cover the precise method of scaling this armor for a perfect fit regardless of your body type
