Biqu Magician Spool Holder Shifter

I made a little modification to the spool holder of the biqu magician. The idea is to be able to use 1kg spools.

Bom:
1 x M5 nut
1x 14mm/16mm M5 SCREW (optional you can use the screw from the spool holder that bring the b.s. magician)
1x 10mm

The m5 screw is looking up due I did notice m5 12mm or 14mm length screws.
