I made this coin in Tinkercad so I had something to hand out to folks during MiniMakerFaire Columbia this year. NeoPortnoy is the name of my Youtube Channel about 3D printing I have along with my daughter. Right now, we're in the process of building a D-Bot, but we also do product reviews and timelapse printing.
You can check us out at www.youtube.com/neoportnoy3dprinting And we'll be at the Columbia MiniMakerFaire April 30th just walking around. If you plan on coming, hit us up for a makercoin!
