Funny QR Code Coin

This is a great joke to play on friends, its a funny QR code coin. I made this to prank my metal detecting friends, I made a hole on the inside that fits a US Quarter. if you want to put a Quarter in it have your printer pause at layer 20 to insert. If you do not want the quarter inserted just turn on supports and it will fill the hole. Thanks for looking and have fun pranking your friends.
