About this model

This is my affordable rock tumbler, designed to tumble 3D printed parts, printed in ColorFabbs metal filled filaments (BronzeFill, BrassFill, CopperFill). It is also possible to add a 'golden' shine to regular PLA when the parts are tumbled with brass screws. It should be possible to build this tumbler for less than € 40.- which makes it much more affordable than 'professional' tumblers that can do nothing better than this one ;-) Please find the full instructions including the BOM here:
