Clamp for NEMA 17 Stepper Motor

UPDATE: I've added a 1.5 mm thick version, which is significantly lighter than the original 3.0 mm thick clamp. The thinner clamp is extremely flexible even when printed with PLA. Although this design has various applications, I used it as a quick and non-permanent solution to prevent the X carriage wires from dragging along the edge of my printer and pulling down the carriage. Here are the specifications for this clamp: • It measures 10 mm in width. • The layer height is set at 0.2 mm. • It has a solid infill of 100 percent. I printed it using PLA, and the result is a thin clamp that can flex and slip around the body of the motor without breaking. For my specific use case: • Attach the clamp to the extruder motor. • Secure the clamp using either an M3 screw and nut or a zip tie. To attach the coil to the clamp, I used zip ties. To increase the rigidity of the wiring, I slipped a long strand of filament into the wire coil/sleeve/wrap. This worked perfectly, as it kept the wiring rigid and higher than the hotend nozzle. Finally, I loosely bound the PFTE tube and the wire coil together using Velcro straps, allowing both to flex and rotate around each other as the X-carriage moves back-and-forth.
