I made these to fit my 2020 S3. They work perfectly on it!

This is designed to use M3 X 20 hex socket head screws and M3 nuts to help clamp it tighter to the stock paddle.

Some websites say that other models might have the same paddles. I do not know FOR SURE but these are some possibilities I've seen"

2016-2020 A3, A4, S4, A5, S5 and maybe even some R8.

Many plastics will warp in a hot car! PLA won't work at all. PETg probably won't. I've even had ABS paddles start to sag but other parts I've printed in ABS do ok in the car. I printed these ones in PC.

ALSO - The vertical lines are on purpose. This is from printing them face up which makes it sit at an angle and then having “ironing” turned on.
