Magnetic Easy Swap Face Button

 A simple 25mm button with interchangeable button face. A pair of 6mm(Radius) x 3mm(Thickness) magnet is all that is needed to make one!

 Magnet should be a nice press fit. Easy to press in with just enough friction that it would fall out when changing face. If yours are too tight or loose, adjust the clearance in included cad file. Enjoy!
