Tired of having to use a exact-o knife to clean off your 3d printed parts?
Well then, just throw you parts in a 1 quart paint can with some rocks, wait several hours and voilà! You have partially cleaned parts that still need to be deburred. err, well .... Maybe I did something wrong. I am sure you will 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 have had mine running now for a coupler hours. I don't know if the parts are getting cleaned but I do know that it seems to be functioning as expected. I will probably be selling the kits. I don't really know what to use as an abbrasive. 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 will head to Harbour Frieght and get a bag of walnut shells tomorrow.
REV 2.0 Coming Soon
Improvements in version 2:
addition of a 3rd gear
a new frame
all new gears
Gear box cover
Electronics upgrade including Speed control*
*depends on if the parts come in before I am done
