A simple and practical sandpaper attachment. With a diameter of 60 mm, I don't recommend using larger sizes, as the motor doesn't have enough power at lower speeds. It's also not advisable to use denser fillers, as the centrifugal force and bearing load would be too high, requiring very precise and laborious balancing. It can be printed using any material. This one was printed using inexpensive PETG from the Czech company Majkl3D.
