Wire Strain Relief for Anycubic Kossel XL Print Head

Wiring strain relief for the print head wiring of an Anycubic Kossel XL. I tried to make do without something like this for a while, but then my print head sawed off the heater cartridge wiring while I had a print running in an odd corner of the build plate. Ferget that noise!

This has some nice relief top and bottom, with a slot to stuff the wiring in sideways and retention for a ziptie.

The holes are 12mm apart and sized for M3 bolts, so double-check your printer head's hole spacing.
