Aluminum Extrusion Rock Tumbler (with control panel and variable speed)
thingiverse
I needed to tumble some rocks so I figured I would make my own tumbler. This build primarily uses parts I had on hand, so that's where many of the design decisions came from. All parts can be easily printed with PLA and were all printed on a Prusa i3 MK3S. Check below for additional parts.
