BMG Extruder Cable Routing

Remixed the **PM_v1.3_Bondtech_RH_Adapter** so that it;

1. Constricted movement of the cables coming from the tool head. The opening diameter of the cable route is 9mm.

2. Is smaller, so the tool head doesn't collide with the vertical extrusions. Keep in mind, you would need to have a pancake stepper for this. I have made a remixed version of this without the cable route: https://www.thingiverse.com/thing:4851663
