3D printed Vibration Rock Tumbler with magnetic drive

Welcome to my YouTube video about the 3D printed Vibration Rock Tumbler! The 3D printed rock tumbler took about 4-5 months to develop. The goal was to polish rocks to an impressive shine, which takes some time. During the development phase, various challenges arose, in particular problems with spring breakage. Fortunately, these problems were successfully resolved and the Rock Tumbler has been working perfectly for several months now.
The Rock Tumbler is controlled via an Arduino. By using two potentiometers, the on and off time of the magnet can be precisely controlled. This enables precise adjustment of the frequency and amplitude of the vibrations. A spring system with compression and tension springs makes it possible to adjust the preload of the tumbler and thus the stroke very precisely. This is one of the main advantages of my 3D-printed DIY tumbler, as the machine can be perfectly adapted to individual needs. From coarse to very fine vibrations, everything is possible with this device.
