GE JB750SF2SS Burner Control Knob Insert

This is a plastic insert for a GE gas oven burner control knob. The GE model I have is JGS750SEF5SS and one of the knobs was spinning freely since the little plastic insert had worn out. This replaces that insert and allows the knob to work again. Not sure if the replacement parts have the same insert since this worked and didn't need to order one but the replacement parts were: WB03X27192, WB03X20724

Print settings on my MK3S

-4 perimeters
-0.15mm layer height
-PETG
-0.4mm nozzle

Installation

The original insert is glued in pretty tight. I had to use a pick and pliers to get it out. A heat gun might help if yours is really stuck. The print was snug enough that I didn't use glue in the knob.

This took a bit of trial and error to get the right size. Feel free to take the Fusion360 file and modify to suit your needs.
