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 block (shipped part). Optional 20 mm spacer for ~50 mm packs. Fit both M5 thumbscrews: 2 V-mounts are a heavy load.

HOW IT WORKS
  Holds 2 full-size V-mount batteries (98-150 Wh, about 98 x 136-140 x 50-66 mm) standing up in two pockets, each 104 x 72 mm and 80 deep. The battery stands about 56-60 mm above the rim, so you grab it one-handed by the top and pull straight up. The bin hangs below the deck on a 10 mm back plate that bears flat on the cart side, so the weight sits low. Three 7 x 52 mm drain slots per floor and two vent slots per front wall.
  Each pocket is 72 mm deep front to back, so a 66 mm pack has about 6 mm of play. For 50 mm thick packs (IDX DUO-C98 class, 49.5 mm) drop the 20 mm spacer in behind the battery: that leaves about 2.5 mm of play instead of about 22 mm. The spacer is 20 x 90 x 96 mm (about 72 g) and has a pull hole in the tab above the rim.
  Two M5 insert holes at 80 mm either side of centre. With about $1000 of bricks on it, fit both thumbscrews.
  Cart facts

  - Sticks out 88 mm from the cart side
  - Hangs 74 mm below the deck
  - Flat cart side needed below the lip: 74 mm
  - Overall 105.7 x 226 x 116 mm: needs a bed of at least 230 mm
  - Rim 12 mm above the deck; batteries stand about 70 mm above the deck
  - Recommended on the cart end (88 mm out is a lot for a doorway side)
  Retention: held by gravity unless you fit the M5 thumbscrew. A short M5 heat-set insert (6.4 mm hole, 9 deep) goes into the deck-side face of the inner flange; a nylon-tipped M5 thumbscrew through it clamps the lip, so the part cannot lift off on a bump, slide along the lip or rattle. Check your lip is at least 16 mm tall first.
  Fits: Backstage Equipment and Magliner-style carts with a 3.4 mm upright shelf lip. The mount drops onto the lip from above: 3.7 mm slot (0.3 mm clearance), 26.6 mm deep with a round end, 0.5 mm chamfers at both slot ends.

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.
