I remixed some of the ancillary parts. The shortened BMG handle was still too tall and ran into the side of my printer so I made one that is a bit shorter. I also found that the idle gear was just rubbing so expanded that area.
My wiring looks pretty bad, so I extended the skirt on the PCB cover to hide the mess.
I added a filament pressure knob extension that uses a 40mm long hex head.
For those using 6mm OD x 4mm ID PFTE to guide filament a tube connector that fits snuggly into the top of the BMG extruder.
