Creality K1 Max Riser + Filament Sensor Relocation

I really liked the unibody style of riser and so I printed AP's remix of a K1 riser, but I found the distance between the corners was a bit too big resulting in the legs not fitting into the four corners of the printer.  This has a filament sensor relocation mounting point and glass slider rails.
