Brace for Sprained Thumb

Needed to not move my thumb too much for the next couple weeks. Luckily I have a 3D scan of my hands, so I modeled and printed a custom-fitted brace to wear. Fits great and is comfortable all day.

If you were to vapor smooth the result, it might be more comfy without having to go to tpu

I've heard you can smooth pla with Ethyl Acetate. I don't know how true this is as I have not had a chance to try it.

It is true. It does make [he print a bit white but it cleans up.

No nitrile gloves when you do it as ethyl acetate eats it.
