The MR129 Type B – Sentinel Front Lip is an original MR129 design developed exclusively for pre-facelift Mercedes-Benz R129 models (1989–1995). Inspired by the bold proportions of period European tuner styling while engineered entirely in-house, it delivers a wider, more commanding appearance without compromising the timeless character of the original chassis.

Every component has been developed using a high-resolution 3D scan of the factory bumper before undergoing extensive CAD refinement and multiple prototype iterations to achieve OEM-inspired fitment. Designed specifically for additive manufacturing, the model is optimized for efficient printing, straightforward assembly, and professional-quality results.

This listing includes downloadable STL files only. No physical parts are included. The files are intended for customers with access to a 3D printer or a professional printing service.
