Fan Knob for Noma stand fan

Our brand new Noma fan from Canadian Tire came with a defective switch knob. We lived with it that way for 8 years, turning the shaft with a pliers or hurting our fingers... until I bought a 3D printer and solved the issue. This knob looks nice and works well. Print it in any color of your choosing.

Switch has a 6.3mm dia shaft, with one side squared off; you can see this in the pictures and CAD renders.
