I use a lot of laser cut parts and they always have a burr on the underside. So I made a rotary tumbler to finish a lot of parts simultaneously. The builder only took about half a day and is well worth it. Now when I take some parts of the CNC I can just throw them in there and not worry about de-burring anything. https://youtu.be/uXZv-Av81ro
There is also a full Instructable in the description.

Why did you use a threaded rod and not just a solid rod for the drive?Quote:

He'd toss in some sand and tumble away.
Tumbler works well, and granite is a good substitute for commercial ceramic media. That it produces a good surface texture is equal or better proof than deburring corners.
I have one suggestion; one to three helical fins inside will increase the 'agitation' and reduce processing time. Rivets and silicone sealant will do the trick.
This is something that I have always wanted.Maybe one day I will build one?
