Mechanical — 3D-printable Mercedes-Benz parts

Protective cap for the exposed upper shock-absorber bolt, shown installed by the creator and printed in PETG to tolerate engine-bay heat. The source gives no suspension variant, bolt dimensions or OEM reference. Compare the bolt and surrounding travel envelope, use engine-bay heat-, fluid- and vibration-resistant material and verify the cap cannot loosen, trap corrosive moisture or interfere with suspension inspection or service.

Standard- and loose-fit replacement grommets for mounting the hydraulic self-levelling suspension oil reservoir on estate cars. The creator identifies the exact child as A1299971681. These grommets support only the reservoir, not a suspension load path. Use oil-, heat- and vibration-resistant flexible material, match the mounting hole and reservoir pin, and inspect for leaks and secure retention after installation.

Spacer ring developed to retain a near-match replacement dust boot on a 126-series rear self-leveling-suspension hydraulic strut when the original boot is unavailable. Source photographs show the physical ring and boot installation. This is a protective-boot adapter only, not a suspension load path. Match the replacement boot and strut dimensions, use oil-, weather- and fatigue-resistant material, and inspect hydraulic lines, clearance, leaks and boot retention before returning the car to service.
