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: Default: one piece with the Backstage/Magliner cart-lip mount, strongest. Optional M5 thumbscrew lock in the mount. Prints standing on its end.

HOW IT WORKS
  Hangs the Solidcom HUB base (259.9 x 180.5 x 65.5 mm, about 1.3 kg) on the cart side, standing on its long edge with its big face toward the cart.
  How it holds
  Two end cradles, a left and a right (mirror images), slide along the lip to the hub's length (outside span 271 mm for the HUB8S). Each is an L-shaped channel 68.5 mm deep with a floor, a 50 mm front lip and an end wall only 30 mm tall. The top of the hub stays 6 mm below the deck, so nothing catches on the shelf edge.
  Antennas and ports: the cradles only touch the bottom corners and the lowest 30 mm of each end. Antennas can point up from the top or down from the bottom, and the cables plug into the bottom face between the two cradles. Put the display side up so you can read it from above.
  On a moving cart: the hub has to lift 50 mm to clear the lip. For a truck ride, run a 25 mm hook-and-loop strap (about 600 mm) round the hub and each floor: it passes behind the hub between two ribs on the panel, over the top, down the front through the notch in the lip and under the floor in its groove.
  Numbers

  - Sticks out 88 mm from the cart side
  - Hangs 195 mm below the deck
  - About 230 g for the pair (115 g each; PETG estimate)
  - Each part 106 x 40 x 237 mm (out x along the cart x tall); prints 40 mm tall, footprint 106 x 237 mm

  Test pieces section of the site (or this part at low infill) and check it on your own gear.
