The Mercedes Benz SL series (R129) from 1989 to 2001 now have a new replacement thanks to 3D Printing Technology.
From T3DPC we offer you the power seat pushbuttons for both sides printed in resin. For such small parts there is no part number or possibility to buy it without purchasing the whole power seat module till now.
Resin is the ideal material for such application because of the resolution and detail required.
Right and left side are considered from inside the car looking at front, check the image. The set include all the parts from each side.
To install it, you just have to push it at the position till you hear the click.
