The D Pad has a super slim margin for error. I edited one side to shave off a small amount. I printed the original print way to many times and this one goes together nicely without having to shave off filament.

Printed at 85% size so all 4 would fit on one plate.
3 walls
Whatever Infill you like.

DO NOT USE FUZZY WALLS on the the D Pad. I did for the other parts.
