I made these for my printer I rewired and extended most of the wiring. they will clip on the inside of the thin side of the T-slot rail one leg on opposite sides. Or if you like they will wedge into the wide side of your T-slot, one leg in each grove side by side. both ways are secure. I recommend using PETG at least 20% infill. And as always enjoy.

these do have thin spots at the base of the clip so are a bit flexible to clip the wire harness in, that is also a weak point so be mindful.
