Work-Light Perch, Stow Bay, Band Cleat and Glow Rim - Backstage cart lip (one piece, strongest)
======================================================================

What it holds: Perch your headlamp on the cart as a work light aimed 35 degrees down over the deck, stow it face-down in the bay for rolling, or hang it. The band wraps short on a cleat, and a glow rim helps you find it in the dark.

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: Strongest: one piece with the Magliner / cart-lip block, the holder fused to an 8 mm back plate that bears on the cart side down to the holder bottom. Sits at the same height as the swappable version on the Magliner adapter, 7 mm closer to the cart. Fit an M5 heat-set insert + M5 thumbscrew. Prints upright, floor down like the swappable version; use build-plate-only supports under the 14 mm deck-side flange of the lip block only. The glow rim is the same for every version.

HOW IT WORKS
  Your hands-free light, always in the same spot and easy to find in the dark.
  Work light: set the lamp face-down on the two ramps that rise from the horns. Gravity holds it in, and a toe lip stops it sliding. The lens aims 35 degrees below horizontal, in over the top deck. The beam clears the cart lip and lands about 40 mm inside the deck edge.
  Stow (for rolling): drop the lamp face-down into the level bay between the horns and run the band ends over the horns. Then wrap the hanging loop short over the two cleat posts on the front. Nothing swings or snags. The bay is open underneath, so it never holds water.
  Hang (parked carts only): drop the band over both rounded horns. The 12 mm front lips stop it sliding off.
  Glow rim (optional): a flush strip of glow-in-the-dark PETG that pegs into the front bar. Nothing sticks up to snap off.
  Fits bands up to about 27 mm wide, and lamp bodies about 42-58 mm wide and 30-40 mm tall (Petzl Tikka, Black Diamond Spot and Energizer size class: check yours).
  Mount: a DOCK tongue on the back (a 38 mm, 45 degree dovetail with a click latch). It fits every DOCK carrier adapter in this collection: the Magliner/Backstage 3.4 mm lip adapter, the ToughBuilt bar adapter and the 19-32 mm tube adapter. Drop it into the receiver from above until it clicks. To swap it, push the release tab and lift it out. For anything heavier than 1 kg, or on a lift gate, fit the M5 lock screw on the receiver.
  Size: the saddle sticks out about 70 mm from the cart side and hangs 56 mm below the deck. A perched lamp reaches about 91 mm out and 102 mm above the deck. About 97 g (rim 1 g).

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.
