Hooks for Drying Rack, 20 mm diameter

i hope i don't bother you with my non exiting things, just optimizing my place a little bit.

For my second drying rack with a 19mm diameter a second version with a 22mm diameter hook hole.

- also this design is more lightweight
- the montage holes are now quite bigger to get different screw drivers to work with.
- the design should still be over-dimensioned

i think it's still stable enough and should not break
