Rusty Old Box Fan Knob
Description
We Have A Number Of Aging "Lasko" Box Fans. One Of The Injection Molded Knobs Failed. The Plastic Became Brittle And There Wasn'T Much Of It. I Made This Replacement Knob In Onshape, Which Should Outlast The Fan. Unfortunately The Switch Underneath Was Not A Simple D Shape, It Was Much More Ornate. I Did My Best To Replicate It And Was Worried That It Required Details Too Small For My Printer (Prussa I3Mk2) To Reproduce. It Works Fine.

I Fixed The Model Before I Posted It. I Recommend Abs For This Purpose, As It Is Less Likely To Crack And Fail. But Pla Should Work Fine. Be Sure To Print This "Top" Down. Support Is Not Required.
