Today, I show you just how I size helmets and cosplay parts for 3D Printing using a little program called Blender.
You can download blender here: https://www.blender.org/
This model was done by Niko Industries. You can go to his site and get some free models, or better yet sign up for his subscription service and get access to the whole library (no ad, just love his stuff).
