Rotring 600 Slim Tip Protector Cap

I wanted to protect the thin tip of my Rotring 600, and the other caps on this site seemed kinda big. I tried to see if I could use the shape of the tip to make something that blends in with the pencil, but snaps into place and stays on well.

I think the result is pretty good. It might wear out eventually and loose it's grip, but it's maybe a 10 minute print that uses minimal filament and thus very reproducible.

Supposedly, printing it in TPU helps it both grip the pencil, and avoid loosening from wear and tear.
