I have a bad habit of picking my nails down to the corner and playing with the remaining nail, which tends to be painful and obviously not healthy to do, so I decided to create this simple ring with a small angle on it that I can pick at to try and mimic the same feeling. It seems to be working for me.

Highly recommend printing in TPU for strength and comfort but works ok with PLA, make sure you smooth the pick point out a little as it can be quite sharp. If you have any issues with bed adhesion, enable brim outer only.

If it's too thin, slightly resize the z height.

I'd advise printing multiple as they are easily lost.

I've also added multiple sizes, a mirrored versions for opposite sides of the nail, and a multi pick point version.

I plan on making one with more curvature so the pick point isn't as sharp.

Hope it helps :)
