Tumbling a 3D printed copperfill skull

When you print 3D parts with copperfill or bronzefill you get a rough surface.
To get the shiny smooth surface, you need to polish the parts. This works best with a tumbler filled with small screws. I also tested tumbling with sand, but the result is not as good with screws !

you should try mixing a few drops of some liquid car wax in with the screws and see if it helps polish it differently

NICE! how long did you put the parts in the tumbler for? and just any type of stainless screws will do?
Thanks for making this

Alvin Thai I tumbled the part for around 8 hours. And yes, you can use any type of small screws. Try it out and have fun!
