Bambulab A1 Spool Handler

This design to place the spool over the top bar of the A1I have re-used the small nozzle that is provided with the vertical handlerto complete the assembly you need 8 pz of 5x10x4 mm ball bearing,and 5 px of M3 x 15 mm screwsspool will rotate freely over the two small rolls. that way you can use every filament even if with non-standard size.
