The file 'Universal Magnetic Hook 3D Printer Model' is (stl) file type, size is 462.0KB.
This is a universally usable hook.
Besides the printed part you need a magnet.
I used a 10x10x4 mm neodym magnet. But sizes up to 14x14x4mm should fit easily.
If not resized, the slot in the part is made to fit am 4 mm thick magnet.
The thin wall of the slot is designed for a 4mm nozzle.
CARE:
The Orientation of the print should consider the way, in which the thin wall of the slot is printed.
I uses these low-priced magnets, which, in my case lift about 0,5kg:
You can also fit a cycle shaped magnet with a diameter of ~10mm as long as its 4mm thick.
