Cart Power-Bank Station with Cable Keeper and USB-C Plug Park - Backstage cart lip (one piece, strongest)
======================================================================

What it holds: Spring-finger sleeve for 10k-20k power banks. A captive shock-cord loop holds the bank down, clip-in side shims stop narrow banks rattling, a window shows the charge lights, and a cable horn has a USB-C plug park.

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 fused to an 8 mm back plate that bears on the cart side down to the holder bottom. Sits at the same height as the swappable version on the Magliner adapter, 7 mm closer to the cart. Fit an M5 heat-set insert + M5 thumbscrew. Prints upright, floor down like the swappable version; use build-plate-only supports under the 14 mm deck-side flange of the lip block only. The side shims are the same for every version.

HOW IT WORKS
  Phones die on long days. Docked on the cart, the bank and its cable are always in the same place and never get dropped.
  Drop it in: two spring fingers on the back wall press the bank against the front lips. It fits banks 54-74 mm wide and about 16-30 mm thick. Taller banks just stand proud of the top.
  Hold it down: a captive 3 mm shock-cord loop runs through two side eyelets and is knotted underneath, so it never gets lost. Flip the loop over the top of the bank and it holds the bank down against the floor, so it can't hop out over thresholds, ramps or lift gates. A cord lock sets the length for a 92 mm or a 166 mm bank. Flip it back to lift the bank out.
  No rattle: clip-in side shims (4 and 7 mm) hook over the wall tops. Two 7s take a 60 mm bank, 4 + 7 a 63, and two 4s a 66.
  See the charge: a 50 mm front window shows the lights. Cable straight down: a 44 x 25 mm floor slot lets the plugged-in cable exit below, and lets rain drain out.
  Cable keeper: hang the coiled cable on the side horn, click the USB-C plug nose-down into the park pocket in the horn tip, and snap the cable into the pinch clip.
  Keep it in shade below the lip: heat ages batteries. It is a holder, not a rain box.
  Mount: a DOCK tongue on the back (a 38 mm, 45 degree dovetail with a click latch). It fits every DOCK carrier adapter in this collection: the Magliner/Backstage 3.4 mm lip adapter, the ToughBuilt bar adapter and the 19-32 mm tube adapter. Drop it into the receiver from above until it clicks. To swap it, push the release tab and lift it out. For anything heavier than 1 kg, or on a lift gate, fit the M5 lock screw on the receiver.
  Hardware: about 350 mm of 3 mm shock cord, plus 1 spring cord lock.
  Size: sticks out about 54 mm from the cart side and hangs 54 mm below the deck. About 58 g (shims 7 g and 11 g).

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.
