AMZN: abrasive stones: https://goo.gl/aq2xmf

hi in thsi video i am going to show you how i solve the problem of the rust that is covering 2000 screws.
i took a kitchen pot very heavy drilled 3 holes, mount 3 springs that act as a soft base for a donut shape cake container,
i qill fill this container uscing abrasive quarz stones.
you can also use other materials.. like sand.. or other metal parts.
this manchine can be used not only for rust removal but also to finish polish 3d printed parts such as Wood PLA, CarbonFiber PLA. TPU, PETG, or PLA, ABS. or other Types: like PLA Filament,or Silky PLA Filament, Wood PLA Filament, or Carbon Fiber PLA Filament, or Flexible TPU Filament, or PETG Filament

just trow them in the machine e let them sit for 45 minutes..
