SpeedDrive For TronXY Pro 2

This is (yet another) remix of sashalex007's rather super direct drive mod but this time for the TronXY Pro 2 (Ender 3 clone with larger build pate and more secret sauce) with the added bonus [drum roll please] that it comes with a .blend file that will can be edited and tweaked in Blender 2.8x onwards.

Other tools will work: at a pinch.
