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
  Clamps go on from below: open the A-clamp, push it up over the 12 mm bar with one jaw in the 28 mm U, and let go. It hangs handles-down. To grab one, squeeze and pull down, one-handed. Holds about 4 #2 or 6 #1 A-clamps along 200 mm. Use it on the top or middle shelf (the handles hang down the cart side).
  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 3.8 mm slot (0.4 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: 50 mm (part); about 70 mm with clamps on
  - Hangs below the deck: 45 mm (part); #2 clamp handles hang to roughly 200 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 (two on this rail). To lock it, melt M5 short heat-set inserts into the two bores (6.4 mm hole, 9 mm deep) on the shelf-side face and turn nylon-tipped M5 x 16-20 thumbscrews 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 thumbscrews on a rail you use all day. Taking a clamp off pulls down and seats the rail, but pushing a clamp back up onto the bar pushes the rail UP, and it only has to rise 26.6 mm to come off the lip. The two M5 thumbscrews stop that.
  This rail's slot is 3.8 mm (0.1 mm wider than the rest of the series) so a 200 mm print with slight bow still drops on.

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.
