X-axis Motor Mount for Wanhao D9/Monoprice Maker Pro

It's no secret that the hot-end on V1 and V2 Wanaho D9s are hot garbage, with quite possibly one of the longest moment-arms I've ever seen in a system like this. After converting my Monoprice Maker Pro (D9 v1 clone) to a linear rail on both X and Y-axis, I noticed that the ABS carriage continued to break due to… you guest it, torque.

The solution? Well, short of designing a one-off x-axis carriage, myself, which I am woefully unquallified to do, I went and bought into the Hero Me Gen 7 and printed that out. While this is a great hotend, it only introduces additional issues, as the standard carriage mount for a linear rail doesn't really interact well with the default motor mount and pulley system.

So, I went ahead and modified the carriage mount for a top mounted carriage, included the specific belt holders on the carriage, and now use that to hit the x-axis end stop.

This is the v4 design, as V1 was a simple flat plate, with V2 and V3 including the top rail attachment points, but making it quite difficult to print as I used some rather idiotic geometry because I'm definitely NOT a mechanical engineer.

This version should be far more robust than V3 (which I will include a picture of, just so y'all know how dumb an engineer can be when they're dicking around with triangles), and looks damn decent at the same time.

Once I figure out how to export the step file from the Fusion360 design, I'll include that, as well.
