Happy Deadpool Day! I haven't seen this design here so I drew up this Deadpool Emoji coin in Fusion 360. Printed with different layer colors using Prusa ColorPrint.
If you'd like to print this with different layer colors, I started with red PLA, change at 3.4mm to black PLA, then change at 4.2mm to white PLA.
Update 5-29-18: I added a keyhole tab at the top for a keychain.
