Hi there, this is a bubble machine that you can make using motor from an old PS2 controller.

You will need:

• A 12v power source to give to the motor his max RPM
• 2 motors from and old PS2 controller (see picture)
• A 230 Ohms resistence
• Print base part (with support)
• Print one of the spin wheels in the files
• Print a propeller, I've used this one made by RossThomas

The assembly is pretty simple, here is a video of the thing working :) https://youtu.be/WZkKWL16Bgo
