I love Another toolhead umbilical! It's exactly the parts I wanted for my Voron Canbus conversion.

Looking at the BOM and the bottom bracket, I'd rather use a threaded insert for the cable clamp rather than source a square M3 nut – in my 10+ years of 3D printing I haven't collected a single one of these. The top bracket uses a threaded insert, so I modified the bottom bracket with a spot for one also. Works perfectly!
