Carrello Omega back adjustment hinge

Problem: The mechanism for changing the backrest angle in Carrello child seats is under enormous stress. Sudden movements or the weight of a child can cause the plastic teeth inside the hinge or the housing itself to crack. The manufacturer does not supply these internal components separately, suggesting replacing the entire chair or looking for a donor at a disassembly site. Solution: This 3D digital model is a reinforced replica of the internal adjustment joint. It is designed taking into account the weak points of the original part and allows you to restore the functionality of the chair while maintaining the safety and comfort of the child. Model specifications: Compatibility: Carrello Omega R child car seat (as well as some similar models from the Carrello line). Purpose: Restoration of the backrest fixation mechanism (Recline Adjustment). File format: STL (high fidelity, tested for compatibility with mating parts). Design: Thickened walls in areas of greatest stress. Recommendations for 3D printing: The safety of the child is a priority, so the choice of material is critical: Material: Only engineering plastics are recommended: Nylon, PA6-CF (polyamide with carbon fiber) or PCCF. These materials can withstand impact loads and do not crack under weight. PLA and PETG should absolutely not be used - they are too fragile for this unit. Filling: 100% (Solid). Layer height: 0.1 – 0.15 mm. Orientation: Print the part in an orientation so that the fracture load does not follow the layer lines. Benefits: Safety: Possibility to restore the fixation of the backrest, preventing it from accidentally falling. Savings: The cost of printing is not comparable to buying a new car seat. Instant access: The file is ready for download immediately after payment.
