  Notes
    ! Six parts on one plate: 2 stands, the axle, 2 cone hubs and an end cap. The cones wedge into the ⌀55 bore from both sides and self-center it.
    ! Stands and hubs print flat; the axle prints STANDING — use a brim. 3 walls, 15% infill carries a full 1 kg spool.
    ! Assembly: slide hub, spool, hub onto the axle from the PLAIN end, press the cap on (a drop of glue if loose), drop into the cradles. The flange and cap stop sideways walking.
    ! Press a 608 bearing into each hub pocket (⌀22.2 — a firm thumb push). The axle is ⌀7.8 and rides the bearing bores.
