Picture hooks to hang paintings and alike on the wall without using nails and screws.

After printing these hooks, just stick double-sided tape (or nano tape) on the back and they are ready to hang paintings on the wall.

The weight you can hang on these hooks largely depends on the tape you use (this is somewhere between 1 and 5 kg maximum per hook).

Set the infill to 100% to make the hooks as strong as possible.
