Rock Tumbler (No screws) Cheap and Easy.

Building a rock tumbler. -I used PLA but I recommend using PETG or even ABS due to the warping properties of PLA over a long period of time. -The motor I used had a 100:1 gear ratio which is a bit overkill but I wouldn't recommend using anything less than 70:1. Anything less will spin a little too fast. The link https://www.pololu.com/category/116/37d-metal-gearmotors Feel free to remix I'm very interested to see what you guys come up with.
