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 piece with the Magliner / cart lip mount (strongest). Prints standing on its end, no supports. Optional M5 heat-set insert + thumbscrew stops it lifting when you put gear back.

HOW IT WORKS
  A 100 mm strip that hangs a row of C-47s on the cart side. Clip each pin onto the 6 mm fin from below, so it hangs handle-down: pulling one off pulls down and seats the strip harder, and nothing sticks up. 16 mm gap behind the fin for the inner jaw. Holds 8-10 C-47s.
  Nothing sticks up above the arm (12 mm above the deck) outboard of the mount, so there is nothing on top to catch a doorway or lift the part off.
  Fits: Backstage Equipment and Magliner-style carts with a 3.4 mm upright shelf lip. The 3.7 mm slot (0.3 mm clearance, 26.6 mm deep, round end, 0.5 mm chamfered ends) drops straight down onto the lip.
  Numbers to check against your cart

  - Sticks out from the cart side: 32 mm (part); about 40 mm with pins on
  - Hangs below the deck: 45 mm (part); the C-47s hang to roughly 100 mm below the deck
  - Flat cart side needed below the lip: 45 mm (the back plate bears there; check with a straightedge)
  Retention: held by gravity unless you fit the M5 thumbscrew. To lock it, melt an M5 short heat-set insert (6.4 mm hole, 9 mm deep) into the bore on the shelf-side face and turn a nylon-tipped M5 x 16-20 thumbscrew in until it clamps the lip. That stops lift-off from a snag, sliding along the lip and rattle. The screw sits 13 mm above the deck, so your lip must be at least 16 mm tall (measure once).
  Fit the thumbscrew on a strip you use all day. Taking a pin off pulls down and seats the strip, but clipping one back on pushes the strip UP, and it only has to rise 26.6 mm to come off the lip. It weighs about 151 g, so a 1.5 N shove (a one-handed jab with a pin that is not fully open) lifts it. The M5 thumbscrew stops that.

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.
