thingiverse

A tumbler machine to smoothen 3D prints. Works best with prints which are coated with filler or are printed with metal filament (Color Fabb copperFill). As abrasive medium brass bolts are used. M5 bolts and nuts secure housing and brackets to wooden plate. M3 bolts and nuts secure cable and motor to housing. M2.5 bolts and nuts secure gear to shaft. Use shrinking tube or insolation tape for a secure and save cable installation.
