Nema17 cable strain relief brace

thingiverse

My Nema17 stepper motors have their four unshielded cables plugged directly into the stepper with no strain relief. In an effort to eliminate this point of vulnerability, I designed a strain relief bracket that can simply slide over the back of the stepper motor without having to cut plugs and feed cable through anything. The support diameter is made slightly larger than it needs to be in case you add braiding or heat shrink first like I did. You could also wrap some electrical tape or similar around the wires to get a snug fit. https://www.youtube.com/watch?v=Mk8ea1oi5v0
