CARP Fishing Chair Back Adjustment Hinge (Type 1)

Problem: The backrest locking mechanism in carp chairs (Type 1) is subject to enormous stress, especially when the angler leans back. The plastic teeth inside the hinge chip and the backrest stops locking, making the chair unusable. It is impossible to find an original repair kit in fishing stores - usually the manufacturer offers to buy a new chair entirely. Solution: This digital 3D model (STL) is a strengthened version of the original Type 1 hinge. The design has been improved: the contact patch of the teeth and the thickness of the housing walls have been increased, which allows the printed part to withstand more weight than factory plastic. Model specifications: Compatibility: Popular carp and feeder chairs (CARP, Ranger, Flagman and analogues with Type 1 hinge). Purpose: Complete replacement of the internal tilt adjustment unit. File format: STL (high precision, optimized for 3D printing). Design: Exact match to the diameter of the frame tubes and mounting bolts. 3D Printing Recommendations: The chair is used outdoors under constant static pressure: Material: Only engineering plastic is recommended: Nylon (Nylon) or PA6-CF (polyamide with carbon fiber). Nylon has the necessary viscosity so that the teeth do not chip under load. PLA should absolutely not be used; PETG may not withstand cyclic load. Filling: 100% (Solid) - the part must be monolithic. Layer height: 0.15 – 0.2 mm. Post-processing: Cleaning of supports and checking alignment before installation into metal frame. Benefits: Increased Strength: Ability to use higher quality polymers than those found in the factory. Savings: Repairs cost 10–15 times less than buying a new chair.
