6 mm to 19 mm Flexible Plum Coupling Shaft Coupler CNC Stepper Motor 3D Printer Hole (d1 * d2):14mm * 14mm The elastomeric body is madeFlexible Plum Coupling Shaft Coupler Precision Motion for CNC & 3D Printers When shaft misalignment causes vibration, noise, or premature wear in your CNC router, stepper motor drive, or 3D printer, the root cause is often a rigid coupling that cannot compensate for angular or parallel offset. This flexible plum coupling shaft coupler is designed for engineers, makers, and machine builders who need reliable torque transmission without sacrificing
