Cart Snack Bar Dispenser (Standard) - Backstage cart lip (one piece, strongest)
======================================================================

What it holds: Bars stack flat and you pull one from the bottom with one finger. A fly and rain lid clicks shut, a window shows how many are left, and a side pocket holds gum or a small mint tin.

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 joined to it across its full width. Sits at the same height as the docked version. Fit the M5 heat-set insert(s) + thumbscrew. Prints upright, floor down; use build-plate-only supports under the 14 mm deck-side flange of the lip block only. Lid and slide-in front panel are the same as the other versions.

HOW IT WORKS
  A gravity dispenser for Nature Valley pouches, Kind and RXBAR-size bars (up to 48 x 144 mm, 21 mm thick). Load bars flat from the top under the snap-hinge lid. To grab one, hook a finger in the scoop under the front slot and slide the bottom bar out; the rest drop down. A 2.5 mm stop lip and the weight of the stack keep the bottom bar in on a rolling cart. The slide-in front panel has a stock window with count numbers, so you see at a glance when to restock. The lid has a front drip lip and a 45 deg roof behind it, it clicks shut on two detents, and it opens to about 110 deg, where it leans back on its own. Two floor drains. A side pocket (18 x 39 x 56) takes a gum pack, a Tic Tac box or a small tin (Altoids Smalls size; a full-size Altoids tin does not fit) standing up, with a U-notch to grab it.
  Mount (DOCK, twin): this holder is wider than 120 mm, so it has two DOCK tongues 60 mm apart (SYSTEM_SPEC twin pattern). Use two adapters set 60 mm apart with the spacing gauge (DOCK_spacing_gauge_60): two cart-lip adapters A_MLN_lip (3.4 mm Magliner / Backstage shelf lip), ToughBuilt bar adapters or round-tube adapters. It drops in from above and both latches click. To lift it out, press the left latch pad, then the right, then lift. Print the DOCK coupon first to choose the fit. The M5 x 25 lock screw is required: fit it in the right-hand adapter only (the left boss stays empty so the neighbour clears).
  Cart facts (on two A_MLN_lip adapters, 60 mm apart)

  - Hangs 101 mm below the deck; holder top 34 mm above the deck

  Parts: body, lid, front panel. The lid snaps onto its pins (flex the skirts), and the panel drops into its grooves before you close the lid.

  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.
