97 firebird window knob

thingiverse

I'm printing out a replacement knob for the window crank that should fit most GM vehicles from back in the day. It's printed with 40% infill and no supports, so it comes out pretty lightweight. However, the pin needs to be printed at full density if you want it to hold up well. When installing this part, I recommend taking the handle off the door first, then slipping the knob into the crank handle. After that, just add a couple of drops of superglue onto the pin and press it firmly into place inside the knob.
