Universal filament spool holder V2 ( dévidoir support universel pour bobine 2)

This support is pretty universal, it accepts spools up to 99mm wide (put one side of spool on the slot : to avoid moving) and roughly all the diameters (150 to 400mm).
This support can be placed on a desk or mounted on the printer as in my case (glued with some double-sided tape on Anet A10).
Works well even with the filaments little tangled on their spool.
Requires only 4 ball bearings (688Z or 688ZZ 16x8x5mm) :
