I needed an adjustable Tumbler for my rotational casts - so I made one based on Stuff I had laying around.

This one is a bigger prototype of mine. Also there are some electrical parts ad high speeds involved so be careful!

This is an ongoing project so come back from time to time.

The parts can be easily stacked together and should all puzzle easily together as needed. Various combinations are possible - be creative.

 

Additional parts needed:

  1. 2x Motor https://www.amazon.de/dp/B01LXCSBPQ
  2. 1x Speed controller  https://www.amazon.de/dp/B09KNKQ7GJ
  3. 4x ball-bearing https://www.amazon.de/dp/B08V1ZVZVD
  4. 1x USB-C Power Platine https://www.amazon.de/dp/B08FD6381L
  5. 1x USB-C Power Supply 
  6. 4-8 cable ties (optional)

Assembly tips:

  • All measurements are kinda the same. So you can use the parts themselves as spacers for assembling.
  • Insert the motors at last for easier alignment.
  • A Filament for mechanical parts is recommended - PETG or better. 
  • Sanding the motor axis can improve attachment.
  • Heat up the axis before inserting it into the printed axis.
  • For higher speeds I suggest using some zip ties to keep everything secured.
