I have tried a BLV mod and made these parts.

The z-motor mount #2 center was a bit off from the file I got, so I made a slotted version for a more accurate alignment.

The Electronics box can fit the Anet A8 board plus two(2) mosfet boards. The case has adequate space and zip tie tabs for good wiring arrangement. An optional fan mount is also integrated in the cover. Cable holes for wiring access from power to extruder and bed wires.

I have printed it in 0.3mm and flexibility is great.
