MR129 Low Profile Knee Bolster – Mercedes-Benz R129 (1996–2002) – Digital STL File

More Legroom. Clean OEM+ Styling. Print Your Own.

 

The MR129 Low Profile Knee Bolster is designed to provide additional driver legroom in the Mercedes-Benz R129 SL-Class (1996–2002) while maintaining a clean, factory-inspired interior appearance.

 

By reducing the bulk of the original driver-side knee bolster, this redesigned component creates more usable knee and leg clearance, making it an ideal upgrade for taller drivers and enthusiasts seeking improved cockpit comfort.

 

Developed using 3D scanning and CAD engineering, this original MR129 design is now available as a digital STL file for customers who want to 3D print and finish their own component.

Rather than leaving the lower dashboard exposed, this design offers a clean, finished alternative.
