Poor Man's Hydra/Trident - Hydrant?

The cost of the Hydra Mod is rather large to swallow and, due to some variances in occupation, was a bit much for me at the time of development. Hence, I sought to develop an auto-tramming system similar to the Trident and/or Hydra, with 3 point bed leveling without the use of many if any extra parts. This is the result, and seems to work well enough.

Re-using the components from the original Z drive, and the purchase of a single extra lead screw, we can create a Voron Trident like system, however, this utilizes linear rods and lead screws in the same manner as the majority of consumer printers today.

In addition to this modification I have installed on my build: the Ender 5+ version of the Zero G Mercury One.1, as well as front mounting the X-Rail with slightly extended X-Joints, and the Mad Max Tool Changer modification, I have included some additional items to center the X-gantry rail (it's spaced specifically to my machine [which is 468mm between joints vs 469mm in the model], but is easily modified) in the appropriate folder along with tool head docks for a 54 x 20 mm bolt pattern.

Assembly should be self explanatory from photos in the attached pdf, hoping to improve that as time allows.
