Jazzy Pride Joystick Knob

thingiverse

These two models replace the standard joystick on a Jazzy Pride Motorized Chair (Electric Wheelchair) with a **6.5mm shaft**. I suspect it will work for almost any mobility chair or scooter with a 6.5mm joystick shaft. I designed these because my mother-in-law has arthritic thumbs and these knobs are easier for her to manipulate. I designed the tall one first, but she prefers the shorter one because she can mostly keep her wrist on the armrest while using it. You will need to print with supports **only for the first 3mm** because of the recess around the shaft hole n the bottom. You should **NOT** need supports for any of the outer features -- the ball curve or the knurling.
