I wanted to clean my wedding ring (Tungsten). But it was a lot of work to hold add the polish, scrub, rinse, repeat, and never get great results.

So I invented the drill-bit ring holder. The default is Size 8 thru Size 13.5. The hex-bit for the drill goes all the way thru the whole device so you can't really break off the end without breaking the center completely out of a lot of PLA. The attached picture is from a 6 year old ring cleaned with this bit.

Usage:

• Get yourself some good ring polish. I ended up using some left over Diamond Polish I had left over from fixing a glass table. It's extremely smooth and brilliant. It doesn't cost the earth and you can Amazon it. There is also Tungsten polish that you may already have, completely usable.
• Put your new 3d printed bit into your favorite drill.
• Get a nice clean smooth rag (no microfiber, it just sucks up the polish). A blue shop paper town works great. As do any of the newer paper towels.
• Push the ring on the holder. It will eventually get to the point where it can't move, you are good to go.
• Apply the polish to the towel.
• Spin the drill with one hand while using the other to apply the polish. Use a back and forth action. Do this for about a minute.
• Dry wipe with no polish and see if it looks good. Clean with water.
• Re-apply polish if needed.
• Finish smoothing using a little water only (no polish) to get to a great shine.

For all of those like me who are hard on Tungsten rings, this is a great and simple way to clean them. It works wonders.

Next up: testing on my Wife's silver wedding bands. Wish me luck! :-)
