25mm Miniature base
thingiverse
A base with build in magnets. Insert a neodynium magnet (1.8x5.8 / 2x6 mm) in the base, and let the print continue. This way the magnets will never fall out and you can worry about other things :) This is build with parametres in fusion360 so it's pretty fast and easy to create other base sizes so let me know if that is something that you would want. Price for a printed base is in the 4cents for plastics, and then a magnet on top - so pretty cheap to manufacture :)
