Funny you should mention that!
Because I experimented with tumbling just a couple a weeks ago!

But the thing is, when a print is finished, youīll have a pretty rough surface, way more that say e.g molds. I could print in a higher resolution, almost 3times better than what I print now, but that would take ages.
Itīs faster to file, sand and polish, and now I finally got the hang of it!
Polishing works fine if I move the part around a bit more than metals, it just takes a bit longer to get the "glassy" feel to it.

In the future Iīll invest/or make a tumbler for polishing small parts, but first an upgraded 3Dprinter is on the top of the list!

I also experimented with some carvings, looks like I can do something custom with that.
