Shutter blind turning knob

So I had a turning knob break off so I made a replacement part for my window(s).If you have adhesion troubles you can use a brim.Use concentric setting for bottom layers (looks better)Break/clear off old material from the old rod and put this new one on with a drop of glue. With my settings it stays on even without glue (rod is 3.85mm - the hole in the part is 4mm)Print in PLA or PETG
