Citroën C4 (Gen 1) Tailgate Bumper / Rubber Stop (TPU)
Custom shock-absorbing tailgate bumper designed specifically for the 1st Generation Citroën C4 (Hatchback). This part is a direct replacement for worn or lost factory bump stops, eliminating panel play, vibrations, and annoying rattles when driving over rough roads.

🛠 Key Design Features
Innovative 3-Point Retention Lug: The three-prong retention geometry is designed specifically for flexible materials. During installation, the prongs compress smoothly, allowing easy manual insertion into the factory sheet metal hole (~0.5 mm panel thickness). Once inside, the prongs expand behind the panel, distributing force evenly across three contact points (120° apart). This guarantees self-centering and a firm, vibration-proof grip that won't pop out when slamming the tailgate or driving over bumps.
100% Print & Forget (No Supports Needed): Geometrically optimized specifically for 3D printing in a vertical orientation. No supports required at all, yielding clean, production-ready surfaces straight off the build plate.
Durable & Weather-Resistant: When printed with TPU/elastomer filaments, the part is fully resistant to road chemicals, oils, UV exposure, and seasonal temperature swings.
