During my time in the bathroom, I occasionally bumped my elbow on a metal towel hook. I won't describe the pain. I came up with the idea of improving the hook by adding a ball-shaped cap.

It doesn't prevent accidental bumps, but it significantly reduces the pain.

Printed from PETG with a 0.2 mm nozzle for the smoothest possible look.

The cap is literally pressed in so it won't fall off. No glue is needed.

Printed in different colors, great for kids to quickly recognize towel ownership.
