A simple Steem coin I made for a cryptocurrency project. This was my first ever 3D model and print; it came out perfect! Check out my other coins:

Ripple: http://www.thingiverse.com/thing:1748000

If you like it, print it and share a picture. I've included an empty coin template if you would like to make your own.
