💡 What is a typical use for a rigid motor shaft coupling in hobby motor and gearbox setups?

Rigid couplers are handy for keeping shafts aligned and transmitting torque cleanly under load. - high torque transfer with minimal play - supports 12mm to 12mm shaft pairs in a 90-degree layout - reduces eccentricity when mounted and tightened correctly - ideal for model cars, boats, printers, and gearboxes ✝️
