AW11 Driver Side Window Switch Replacement Nub (“Auto-Down” Feature)

This part is a replacement nub for the driver-side window switch found in the Toyota MR2 AW11 models equipped with the “Auto-Down” feature.
If you’ve found this file, you likely already know what it’s for—but here’s a quick rundown just in case:

The nub sits inside the switch lever, held in place by a small spring. The spring keeps tension on the nub, pressing it against the copper rocker contact inside the switch assembly.
When you move the switch lever forward or backward to roll the window up or down, this nub applies pressure to the copper contact to activate the circuit.

The OEM nubs are extremely small, brittle, and easy to lose or break, which makes this printed replacement a practical fix for an otherwise functional switch. There are other components within this switch that break, so please watch the video I've attached for a more in-depth repair process.

Printing Recommendations

Nozzle: 0.4 mm (or use 0.4 mm settings with a 0.6 mm nozzle)

Material: PETG or ABS recommended

Print Speed: Very slow for best accuracy

Cooling: Use more cooling than usual to maintain shape

Resolution: Higher resolution = better results

Filament: Ensure filament is completely dry before printing

Because this is a tiny precision part, patience and careful printing will yield the best results.
