UPDATE: I have finally accomplished making an SCAD version with text that automatically center and is possible to change. So if you wish to have your own version with monogram just use customizer or OpenSCAD on your computer.

Hi,

let me introduce this simple, yet genius cart token/keychain. I have designed this around size of roughly 1EUR coin or 10CZK. But I guess it will work worldwide. I have wanted something simple and fast to print so I can give this to any of my friends or colleagues to introduce them to 3D printing. Operation is easy, just slide in the slot for coin and then firmly pull back, no need to leave your keys in.

Happy printing and share your prints. Thanks.
