About this 3D model

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
