This 16-piece handle set is intended for TRX-4 pattern model shells and is referenced as TRX4ZSP10. Components are produced by PLA 3D printing to achieve consistent surface detail and scale-accurate geometry for crawler modelling.
Fasteners supplied: twelve M1.2x3 stainless steel screws to attach the handles to thin plastic shells. Screw sizing and count are selected to match the printed parts for model-shell applications.
Assembly procedure: prepare pilot holes with a reamer or fine drill bit to the recommended diameter for M1.2 screws, align each handle, and torque screws lightly to secure. Monitor hole size and torque to avoid stress concentration and shell failure.
Application note: these parts are cosmetic scale components for TRX-4 style bodies and are not engineered for load-bearing or real vehicle use.
