    Affordable Rock Tumbler

    Thank you for the design. I based mine off of your design. I had to design mine because the motor I bought was different. Everything except the threaded rod, nuts and electronics are #3d printed. The frame, motor mount, and pulleys are all ABS. The gears and rollers are Alloy 910. The drum, O-Rings, and pulley belt are all TPU.I added and on/off switchI added a speed controller I added two pulleys and a belt on the other side for dual turningI also added, in the design, a detachable and adjustable motor mount to allow for changing gears and motors.
