Cardan Joint for Infento

thingiverse

This cardan joint is remarkably resilient. The bright red section in its center consists of a standard 30x30 square steel profile (20-30mm in length). To prevent wear and tear on the plastic components, I have inserted hat bushings into the bores. Modified M8 bolts secure the assembly from within, their ends precision-turned to an M6 thread to ensure a snug fit. The bolts are held firmly in place by M6 locknuts.
