Spoolholder for Biqu BX

I have made it so the BTT Smart Filament Sensor can be mounted on top of the roll, to remove all drag from carriage.

Fits the roller from original spoolmount.

I have made 2 grooves to add 2 strips of filament for reinforcement, if you need to cut it to fit your bed.

Fits on either side, needs a t-nut for mounting. Also has space for m4 nut, if mounting a filament sensor.
