I came across another great resource for free, user created 3D models with accessible downloads for end-user 3D printing:
"My MiniFactory": https://www.myminifactory.com/category/cosplay
I discovered it while looking around at alternatives for the Fallout 4 Pipboy. While there's some very great 1:1 scale items (perfect for cosplay), ytec3d's version(s) have many small pieces that don't scale very well if using for custom figures that need a pipboy.
However, there are versions available for that use too, thanks to "Jim". :)
