Beefy GE dryer knob

thingiverse

Our GE dryer came with a flimsy knob, with thin plastic walls, which just felt cheap. Eventually the plastic holding the timer shaft broke. I made this chunky replacement that should hold up better. Transfer the metal shaft liner from the old knob to this one, If you don't have the metal shaft liner anymore, reduce the shaft diameter by 1 mm and set the shaft hole constrict to 0 mm (that's for keeping the metal liner from falling too far). I had to do a couple of test prints to get the hole diameter dialed in. Finally, I printed in PLA.
