Smooth-O-Matic Parts Polisher and Rock Tumbler

cults3d

Tired of having to use an exacto knife to clean off your 3D printed parts? Well then, just throw your parts in a one-quart paint can with some rocks, wait several hours and voila! You have partially cleaned parts that still need to be deburred. Maybe I did something wrong. I'm sure you'll have better luck. This is a video of it working: http://youtu.be/GwR-Y1e6QFQ This is a great low-cost DIY solution for those who don't want to pay an arm and a leg for a rock tumbler. I've had mine running now for a couple hours. I don't know if the parts are getting cleaned, but I do know that it seems to be functioning as expected. I'll probably be selling the kits. I don't really know what to use as an abrasive. I went with a bag of small gravel from Home Depot. The gravel doesn't seem to work at all for me. It might just need a lot more time. I think I'll head to Harbor Freight and get a bag of walnut shells tomorrow.
