Biqu BX Spool Holder

thingiverse

This serves as an upgraded version of the stock filament holder supplied by BTT for the Biqu BX. You will require two 608Z (skateboard) bearings for the roller to function properly. There are slots in the roller made for placing O-rings to increase the grip between the spool and the roller, but this is optional. A piece of advice when printing, on the part "Spool Holder" print the thread section solid or with as many walls as possible. I printed mine with 50 walls (so completely solid) as this is the part that experiences the most strain and wear.
