There's my design of vitval hook, this hook is designed for IKEA Vitval, but it can be used in other ways.

This hook can be used for hang clothes, backpacks and other things.

Printed with Creality K1 with white PET, 75% infill denisity and 0.10 mm layer profile.

Suitable for all material, but i recommend strong material like ABS, PETG and PET.

Any feedback is welcome and... Happy printing!
