3kg Spool Holder

A 3kg filament spool holder. To be used with 4 6000-2RS bearings (10x26x8). Printed and tested this, works fine, the spool is securely placed and won't fall out, rolls smoothly and has low rolling resistance.Used 5 wall loops for shafts to sustain the spool weight.Installing the connecting rods may be a little tricky. The rods have to be inserted Into the holes on the bearing supports and pushed down. I added those rods to prevent the base frame deformation under spool weight after previous testing iterations.I also recommend to polish the seams on the shafts at the spool contact points for smoother rolling
