Filament spool holder

Tired of vibrations of your filament spool? Factory spool holder diameter is too small and any pull (or retract) makes the heavy spool to swing back and forth. This transfers to a vibration of the whole printer.
I designed a spool holder that is mounted to the top horizontal rail of Ender 3 S1, but it can be mounted on any 20x20 v-slot aluminum extrusion.
There are 2 arms with small rollers where the filament spooler seats on. Need to print a mirror of the stl file.
I also added a mount for the filament sensor (can be screwed with the original M3 bolt.
I designed 2 arm types - one is with 525ZZ bearings (8 in total, but can be made with 4) which are screwed directly to the arms with M5x20 bolts. The second type is with gliding bearings which are much easier to mount, but can fall down when the filament spooler is removed.
