Jazzy Wheel Chair basic knob

Simple knob I made for my grandpas Jazzy motorized wheel chair

One file has a 3/16 hole (4.77mm) that should slide right on, the other is slightly smaller hole if you want to scale the knob up a bit

knob diameter was 66mm, about the size of a tennis ball or small baseball

If you would like a different version like smaller hole for joystick mount or larger handle feel free to ask

*would recommend smoothing the part to avoid sweat, dirt and bacteria build up
