The GPM TRX4ZSP10A door handle set is produced in PLA using controlled 3D printing to achieve repeatable geometry and consistent wall thickness. These characteristics help ensure predictable fit and alignment on Traxxas TRX4 shells used in scale builds and testing setups.
Prepare the body by reaming the handle aperture to remove material tolerance, then mount each handle using the supplied screws. Verify alignment before final tightening to prevent stress on the shell and to maintain correct operation under trail loads.
