A filament dispenser (10) includes a spool (20), hub (22), and axle (30). The axle is laterally movable from a first position to a second position. The axle is independently rotatable with respect to the spool. In the extended position, the axle may be attached to a second spool (10′), forming an assembly of operably-coupled filament dispensers. In the assembly, the connected spools are independently rotatable. |
