Physical Proof of Brain Token (3D Printed)

Recently inspired by a 3D bitcoin model I found on Thingiverse I decided to try to make my own faux physical cryptocurrency model.

I created my Proof of Brain 3D model on Tinkercad. I started with a blank coin model posted on Thingiverse by user ManMommy. I scaled the model up from 40 mm to 50 mm. The brain graphic in the center is adapted from an image I found on

It took less than an hour to print the physical representation of a Proof of Brain token.

I will most likely revisit this design later when I start working with metal filled filaments. As I get more experience with 3D printing I am sure I can improve on this design.

If you have your own 3D printer and/or want to make your own version the 3D model I made is available on Tinkercad and a .stl for 3D printing is available on Thingiverse. Both files are under a Creative Commons CC BY-SA 3.0 license. Sharing is caring!
