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 spacers (1 = F750, 2 = F550).

HOW IT WORKS
  Holds 4 Sony NP-F970-size batteries (about 38 x 55-57 x 71 mm) standing up. Each pocket is 42 x 62 mm and 46 deep with a finger notch in the front wall and a drain slot in the floor; the battery stands about 25 mm above the rim, so you pinch it out one-handed. NP-F750 and NP-F550 fit loosely on their own. Drop one 20 mm spacer behind an F750, or two behind an F550, and they sit snug.
  Two M5 insert holes at 60 mm either side of centre.
  Cart facts

  - Sticks out 78 mm from the cart side
  - Hangs 38 mm below the deck
  - Flat cart side needed below the lip: 38 mm
  - Overall 95.7 x 190 x 80 mm
  - Rim 12 mm above the deck
  - End walls 5 mm, dividers 4 mm, floor 4 mm, back plate 12 mm
  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.
