This is a hook I designed to hang guitar bags inside my closet. The base STL included is for the same footprint as the hooks in the cover photos, with slightly increased filleting. This size fits 3M 1" double sided "permanent" mounting tape.

The attached Fusion 360 file is fully parametric and allows for easy configuration of:

• Footprint (width, height)
• Hook size
• Hook length
• Filleting (by way of the above 4 parameters)

Printed with cubic infill and concentric supports. Resolution and wall thickness may affect overall strength - I used 4 wall/top/bottom layers at 0.16mm, your mileage may vary for longer hooks or hooks holding heavier objects.
