All Parts Mini Disc Sander

This is great design by Perinski and I love the rounded case in particular. Unfortunately I bought a larger sized motor than the one recommended in the original design in one of these Chinese shops and had to stretch the case and the bottom by 10mm to fit it in. I also had to move the place of the motor holder as the gear on the head was not in line with the gear from the pulley. While I was re-sizing the outer dimensions I also moved the slot for the power switch at the back of the case to the other side as it was colliding with the back of the motor and added some ventilation slots. A big disadvantage of the original design was that the gear for the pulley was not entirely available and a belt missing so I redesigned it and fixed the pulley with a small grub screw. The 2 parts of the gear are a tight fit and with help of some super glue won't go apart. The belt is best printed with a flex or TPU filament. Finally I added some feet, which - enhanced with some self-adhesive sponge rubber - do their job quite well. The other parts required for building this neat tool you need to take from the original one.
