HOW IT MOUNTS
  BACKSTAGE CART LIP (ONE PIECE, STRONGEST)
    The cart-lip slot is printed into the holder, so it is one piece and as strong as it gets.
    Hold it tilted, hook the slot over the upright lip on the edge of a Magliner / Backstage-style cart
    shelf, and rock it down until it sits flat against the side.

    Notes for this holder: One colour: the plain file. Two colours: _base + _text (same coordinates, load together). Native one-piece cart-lip mount (strongest): drops onto the Magliner/Backstage lip, two crush ribs hold it, optional M4 heat-set insert + thumbscrew. Prints upright, no supports. clip_HZ_label_fit_test.stl is the 20 mm crush-rib fit test, print it first.

HOW IT WORKS
  A SOUND label that drops onto the cart lip so everyone can see whose cart it is. Raised 1.2 mm letters 26 mm tall. The 140 x 45 mm plate sits flush in front of the lip on an 80 mm mount. Its wings come back to 0.3 mm off the lip, so nothing can hook behind them in a doorway, and the plate ends are chamfered 45 degrees. Leave 35 mm of clear lip each side of the mount (no other clip under the wings). No stickers or tape on the cart, so it is reusable on rental carts.
  Cart facts

  - Sticks out 14.2 mm from the cart side
  - Hangs 0 mm below the deck
  - Flat cart side needed below the lip: none (nothing hangs below the deck)
  - Plate stands 45 mm above the deck
  - Overall 31.9 x 140 x 45 mm
  Retention: held by gravity unless you fit the M4 thumbscrew (this family uses M4 instead of the M5 used on the bins). A short M4 heat-set insert (5.6 mm hole, 8 deep) goes into the deck-side face of the inner flange; a nylon-tipped M4 thumbscrew clamps the lip. Two small crush ribs in the slot (0.1 mm press fit on the lip) stop rattle on their own.
  Fits: Backstage Equipment and Magliner-style carts with a 3.4 mm upright shelf lip. The mount drops onto the lip from above: 3.7 mm slot (0.3 mm clearance), 26.6 mm deep with a round end, 0.5 mm chamfers at both slot ends.

TEST THE FIT FIRST
  Carts, bars and tape rolls vary a little. Before a long print, print the small fit test from the
  Test pieces section of the site (or this part at low infill) and check it on your own gear.
