I have designed hooks that are thin and can take a lot of weight.
The hooks are reinforced with ordinary wood screws available from any hardware store.

The hooks are stronger than the Honeycomb Storage Wall itself.

All hooks use the same insert.

The hooks are named after the size of the screw. For example, hook L40D4 should be assembled with a screw of total length L=40 mm and outer diameter d=4 mm.

Each hook has information on its flat face as to which screw it is for use with.

During assembly, the torque from screwing in a screw can be more than your hands can handle. Therefore, I recommend that you use a vice or some kind of clamp to stabilize the assembly.

Hooks are bent up a bit so that when you hang something on them, things do not fall off.

I printed it with parameters:

Layer high: 0,2

wall thickness: 1,2

infill 25%

no supports.

Material: PLA
