GE Dryer Replacement Knob

The knob was no longer turning the timer so I took some measurements and created a scad file to generate this knob.  Pretty simple overall but it is working and we can dry clothes again for cents.

I used 4 walls + made the infill around the stem 90% for better strength as the timer stem is tough to move.

I cannot tell what model my dryer is (haven't found a model # or sticker)

Dryer Models I think this would fit on based on images:

GTDP490EDWS
GTDN500EMWS

Models it might fit on based on Amazon replacement knob list:
GTWN3000M0WS
EGD4600G7WW
DRSR483GG0WW
GTDP350GM2WS
EED4600G0WW
EED4600G4WW
