I converted my Ender 3 Pro to use a Micro-Swiss NG direct drive extruder. This meant more cables running from the electronics box to the tool head. It also meant that the extruder mount on the gantry was free. 

So I designed this mount to corral that big bundle of wires. It has three sets of notches that I sized to fit zip ties so they won't slide around. I use Honey Badger (~13mm) wire wrap to protect the wires. That bundle fits in here pretty nicely.
