GMC Van window crank handle

Broken window crank knobs? Me too. More than once. These are easily printed without supports and snap into the plastic crank arm. Sketched these up in Tinker and they are a tight snap into place. I had PLA loaded so I printed at 80% and they've been holding up. PETG might be needed given the hot environment they live in. Time will tell.

Edit; Print this in PETG. The PLA did not hold up when the weather got cold and the window was frozen. As an aside, there are aftermarket handles available for about $10.
