  Spool      ⌀200 × 60 mm, bore ⌀33
  Axle       ⌀12 × 138 mm

  PRINTING
    Stands, hubs and cap flat as exported; the AXLE stands
    up — give it a brim. Assembly: hub + spool + hub slide on
    from the PLAIN end, press the cap on, drop into cradles.

  Notes
    ! Six parts on one plate: 2 stands, the axle, 2 cone hubs and an end cap. The cones wedge into the ⌀33 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.
    ! No bearings: the hubs spin on the smooth axle. If the spool drags, wax the axle or regenerate with bearings on.
