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 native Magliner / cart-lip mount (the shipped part). Takes a steel 5/8 in baby pin on a captive 3/8-16 nut. Prints on its end, no supports.

HOW IT WORKS
  Gives you a 5/8 in baby pin on the cart for a small 5-7 in monitor, up to about 1 kg. The pin is steel: a 5/8 in baby pin with a 3/8-16 male thread screws into a captive 3/8-16 hex nut, which slides into a pocket from the outboard side. The 70 mm back plate bears on the cart side, so the monitor cannot tip the clip outward.
  The load sits above the edge, so fit both M5 thumbscrews and use a safety line. It is not for lights or anything over people.
  Hardware: 1 x 3/8-16 hex nut (9/16 in across flats), a steel 5/8 in baby pin with a 3/8-16 male thread (12-20 mm of thread, so the stud passes all the way through the nut), 2 M5 heat-set inserts and 2 nylon-tipped M5 thumbscrews.
  On the cart: sticks out 12 mm (the pin stands over the clip) from the cart side, hangs 70 mm below the deck, and needs 70 mm of flat cart side below the lip for the back plate to bear on. The boss stands 58 mm above the deck, plus the pin.
  Retention: held by gravity unless you fit the M5 thumbscrew. Press a short M5 heat-set insert (6.4 mm bore) into the hole on the deck-side face of the clip, then fit a nylon-tipped M5 thumbscrew. It clamps the cart lip so the part cannot lift off on a snag, slide along the lip or rattle. The screw sits 13 mm above the deck, so your cart's lip needs to be at least 16 mm tall.
  Fits: Backstage Equipment and Magliner-style carts with a 3.4 mm shelf lip. It drops on from above: a 3.7 mm slot (0.3 mm clearance), 26.6 mm deep with a rounded end and chamfered ends.

  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.
