This was originally to replace worn out dish cloth hangars. I already had single holes in the wall and designed them to work with a single hole but also included the two hole version if you want to stop them from rotating. My single hole ones on the wall do not rotate when the screw is tight though.

The screw hole is 4 mm so M4 or M3 screw (or imperial equivalent).

I made these very sturdy so will print another set for my replacement coat hooks.

Print these on their side for easier printing and maximum strength.

As always suggestions or questions just message me.

I currently have my 0.6 mm nozzle loaded for quicker and stronger prints. I used 0.3 mm layer height, 3 walls (inner wall line width 0.5 mm and outer wall line width 0.6 mm) and 5 top and bottom layers. This is very strong. Outer walls 35 mm/s and inner walls 40 mm/s, infill 60 mm/s and top and bottom 50 mm/s with a 40 mm/s travel speed.

May seem excessive but the part is load bearing and is only small so will still print fast (about 40 minutes each).

If you are using a standard 0.4 mm nozzle I would print at 0.26 mm layer height, 4-5 walls (with the standard width being 0.4 mm will give the same overall thickness as the bigger nozzle) and 6-7 top and bottom layers.

I used a 12 line brim to keep the thinnest part from curling up with the heat.
