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 upright on one flat face (case bottom + mount bottom), no supports. Optional: M5 heat-set insert(s) from the deck side + M5 x 20 nylon-tip thumbscrew stop lift-off.

HOW IT WORKS
  Long four-cell clear-lid case for Sharpies, markers and hex keys. Twin DOCK tongues.
  Numbers

  - Grid: 4x1 (42 mm cells), interior 168.5 x 42.5 mm
  - Outside: 174.5 wide x 57.1 deep x 29.0 tall (the tongue rises 10.5 mm higher at the back; the latch tab adds 6 mm at the front)
  - 26.0 mm from the pocket floor to the closed lid
  - DOCK: twin tongues at 60 mm pitch (use a twin adapter, or two singles set with the 60 mm gauge)
  - Filament (estimated): base 92 g + clear lid 24 g + label card 2 g = 118 g per case
  How it works

  - Clear lid: see what is inside without opening it. The coloured base matches the rest of your cart kit.
  - Two click-shut latches at the front, so the long clear lid stays down at the corners. To open: pinch both gripped tabs with thumb and middle finger, pull toward you, lift. An upward bump pulls the square tooth straight against a square ridge, so the lid stays shut on a moving cart. Small crush bumps on the rim preload the latch, so the lid clicks firmly and does not rattle.
  - Snap-on pin hinge, so the lid prints separately in clear PETG. The lid opens to 98 deg and rests past vertical on a hard stop.
  - Drip skirt all round the front and sides. Drip-proof, not sealed.
  - Front label slot for a 0.8 mm card (included), which slides in from the right corner.
  - Drop-in floor compatible with Gridfinity (Gridfinity by Zack Freedman, MIT licence): standard bins, our insert set and community bins all drop into the slots. Closed-lid headroom fits a 3u bin with stacking lip, or anything 2u, and keeps bins from hopping out on a bumpy cart.
  - DOCK tongue on the back: it clicks into any DOCK carrier adapter (Magliner/Backstage lip, ToughBuilt bar, round tube, T-slot). Push the adapter's release pad and lift to take the case with you.

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.
