Update! Denim did nothing even after like a month. I tried various other media, round ceramic beads, ball bearings, etc and on the spinning tumbler it always ended up with chips in the 3d print.

I bought a vibratory tumbler a few days ago. I added a mix of walnut shells, corncob bits and fine grit. Then I tossed in a couple of rough stainless steel 3d prints. Initial observation was it looked like I needed more mass in the tumbler and I had a bunch of F- grade poo counterweights so I chucked them all in.

It looks like a cat littler box from a cartoon.

But after two days of tumbling this part came out and it’s very shiny compared to a raw part.

Here’s a comparison of a raw part and the tumbled part.

And a nice shiny angled shot of the tumbled part.
