New Belt Path - Monolith Zero

The last time I talked about how I wanted to improve the toolhead compatibility situation between the 2 platforms. But, I never showed the actual belt path to do it with only a different belt clamp and a Beacon delete.

I want to keep the gantry itself as simple as possible, so there will be no live shafts for 6mm belts. The K3-style tensioners will be on the back of the toolhead itself, which means more Y-travel and fewer idlers.
