This is a replica of the commercial product “Swedhook”. Swedhook is not available in the USA and this was a problem for me - I wanted (and would still willingly purchase) the actual commercial product. 

This utility hook can be used in a massive variety of situations. For example:

• Hang on a door to add a hanger
• Hang in a closet on the rail, allowing you to hang additional items
• Hang on the back of a chair to hold a bag
• Use as a grocery bag handle
• Use as a towel hanger or holder (by hanging on the sides or pushing through the middle, respectively)
• Hang a lantern in a tent
• Hang camp shoes or sandals off a backpack while hiking

This utility hook design is deliberately ambiguous, allowing it to work anywhere you can think. I have used it for hanging clothes while traveling and securing a shoulder bag while riding a sit-down motor scooter.

Printing:

• Perimeters - 3 to 4 is the sweet spot for structural integrity
• Filament - PETG for flexibility
• Infill - 30% gyroid
• Supports - the back of the hook is slightly flattened for ease of printing, with no supports required. 

Scale as needed. The design scales extremely well. Add a brim if you are shrinking it.
