Towel hook

A reproduction of a plastic towel hook.

The second version addressed a fail point that happens over time and made it last longer. However it only moved the fail point closer to the curved part of the hook. This latest version addresses a first layer print issue and adds reinforcement to the new failure point. I have also removed the other versions.

Uploaded stronger version. The original designs cracks after about a year of holding wet towels.
