DIY Rock Tumbler and Polisher

Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:6296848.

Just a quick DIY rock tumbler. Parts include:

• Motor mounting bracket
• Coupler for attaching tumbler shaft to motor D-shaft
• Support bracket for powered shaft
• Brackets for attaching the boards perpendicular

Parts you will need:

• Boards to build the actual thing
• A hole saw or some other way to drill the holes in the boards
• A motor. I used a 12V 100RPM High-Torque DC Motor. I used this one: https://www.ebay.com/itm/183846644222
• A power supply for the motor. I used this one: https://www.ebay.com/itm/264310583780?var=563897081879
• 1" PVC pipe for the 2 shafts
• Rubber bands to make the shafts grippy. You could also use a rubber sleeve/host of some kind or some shrink wrap tubing for this.
• Some 1/4" bolts and nuts for mounting the motor mount
• A M3x10 machine screw to lock the motor coupler to the shaft
