Bits for the nail drill machine for the polishing

thingiverse

These bits work good with a nail drill machine, I don't know if these should be fine with dremel too. Model was designed for the polishing models from the bronze and copper filament. (You can see samples on the pictures above). For the work you need 1 internal part and many externals. Internal hole part have to be fixed after printing. External part have 2 versions with 200u hole and 300u hole for the thick sandpapers.
