CR-10 Hot End Wire Strain Relief Bracket

If you're like me, you have had issues with the crimps on the heater core of your CR-10's hot end. The crimps come loose or the stranded wires fray and your hot end can no longer reach temp. This is likely caused by repetitive heat cycling combined with continuous motion as the hot end travels across the x-axis. The wires come zip-tied to the PTFE tube, but this isn't enough to prevent fatigue.

This bracket mounts between the print cooling fan and the hot end housing using the stock screws
