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
  The Solidcom headsets do not charge over USB: their 700 mAh packs charge only in the battery charging case. These two holders give the case and the spare packs a place on the cart, right next to the headsets.
  Charging case pocket
  The 8-slot charging case (159.1 x 110.9 x 27 mm) drops in standing on its long edge and stands 36 mm proud of the rim, so you lift it out with one hand. It has to lift 75 mm to come out, so bumps do not throw it. A cable notch in each end wall and a slot in the floor let the 12 V lead leave whichever way the case's socket faces, down to a power strip on the cart. Four diamond windows in the front show the charge lights and let warm air out. The 4-slot case (about 90 mm long) fits too, with room to spare.
  Spare pack dock
  Eight pockets for the packs (39.5 x 25.7 x 11.7 mm), standing on end and 15.5 mm proud for a pinch grip. Two rows of four: keep charged packs in the outer row (it has thumb notches) and flat ones in the row by the cart, so anyone can tell which is which.
  Numbers

  - Case pocket: sticks out 42 mm, hangs 82 mm below the deck, 171 mm along the cart, about 178 g
  - Pack dock: sticks out 40 mm, hangs 45 mm below the deck, 128 mm along the cart, about 128 g
  - Both need 45 mm of flat cart side below the lip; each has two mount blocks and two M5 insert bores

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