The first Tool of the Armorer, Calipers

Cosplay Calipers

The essential, custom-sized measurement tool for every serious cosplay maker!

Tired of wasting precious filament on helmets and armor that are just slightly off? Say hello to the Cosplay Calipers. Forged for the modern artisan, this is the fundamental, large-format measurement tool every serious 3D-printing cosplayer needs to achieve a perfect, custom fit every time.

These calipers are specially designed with long, curved arms to easily measure the wider, deeper dimensions of the body—perfect for capturing the width of your head, the depth from your nose to the back of your skull, or the precise shoulder-to-shoulder width required for chest and back armor.

  • Optimal Cosplay Sizing: The large scale is specifically calibrated for measuring key body dimensions needed for accurate helmet and body armor scaling.
  • Simple Assembly: The design consists of just two main arms and a simple bolt and nut mechanism for the pivot point, allowing for fast, easy assembly right off the print bed.
  • Secure Measurement: The pivot is designed to be tightened with the custom 3D-printed nut, allowing you to lock in your measurement before removing the calipers from your body. This prevents accidental movement and ensures you retain a highly precise reading for scaling your digital models.
  • Durable & Printable: Designed to print without supports (on the flat side), this model is optimized for strength and a successful print on most standard-sized build plates. It features embossed branding—Cosplay Calipers—providing a stylish, custom look to your workshop arsenal.

To forge your own reliable measuring tool, we recommend the following sacred geometry and arcane parameters for your 3D printer:
