Hexagonal Surface Keyhook: Remixed and Improved.

A refined multi-level hexagonal key hook mount, remodeled in Fusion 360.

I added bevels to the holes for the hooks and added 0.05 tolerance to the holes themselves, which previously had no tolerance.  Still, you may find you need a hammer to tap the hooks in gently.

The hooks themselves have been also rounded with fillets to reduce the risk of bed adhesion issues and/or poking yourself with the hooks themselves.

Shown here in a mixture of cloudy white PETG and Prusament galaxy black PETG.  PLA should also be fine of course.

STEP and STL included.
