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 native Magliner / Backstage cart lip mount (strongest). M5 heat-set insert + M5 thumbscrew clamps the lip.

HOW IT WORKS
  Air cans tip, roll and end up on the floor of the truck. This holster holds one standard duster nozzle-up beside the cart, so you grab it by the top and pull straight up.
  Accepted cans: 63.5 to 71 mm (2.5 to 2.8 in) diameter. That covers 10 and 12 oz Dust-Off (including the 2.75 in DPSXL), Falcon, Fellowes and store-brand cans. The bore is 72 mm. Two spring tongues are cut into the wall, one on the outboard side and one on the end, each with a ridge near its free end that stands 9 mm proud of the wall. They push the can against the cart-side wall. A slim 63.5 mm can is held with about 1.7 mm of spring preload, and a fat 71 mm can bends them about 8 mm. Either way the can sits tight and does not rattle on a push across a sound stage. With a fat can in, the outboard tongue bows out by up to about 8 mm.
  The pocket is 115 mm deep, past the can's centre of mass, so the can cannot bounce out on a ramp. A closed 3 mm floor with a 10 mm drain hole stops it dropping through, and a 1.5 mm chamfer at the rim makes it easy to drop back in without looking. A 216 mm (8.5 in) 10 oz can stands about 100 mm proud of the rim, which is at deck level. The can is the heaviest thing here (about 0.4 kg full), so it hangs low and close to the cart, as heavy items should.
  Not for 3.5 oz mini cans: they sit too deep to grab one-handed.
  Measure the cans your crew actually buys. Anything outside 63.5-71 mm will either rattle or not go in.
  Cart facts

  - Sticks out 83 mm from the cart side (up to about 91 mm with a 71 mm can bowing the outboard tongue). On a narrow cart, fit it to the cart end
  - Hangs 118 mm below the deck
  - Needs 45 mm of flat cart side below the lip. Anything lower is set 2.5 mm back from the cart and hangs clear
  - Overall 101.0 x 80 x 160 mm (out x along x up)
  - Nothing of the part sits higher than the 42 mm mount block; the can itself stands about 100 mm above the deck
  Retention: held by gravity unless you fit the M5 thumbscrew. Press a short M5 heat-set insert (6.4 mm hole, 9 deep) into the deck-side face of the inner flange. A nylon-tipped M5 thumbscrew through it then clamps the lip, so the part cannot lift off on a bump, slide along the lip or rattle. Check first that your lip is at least 16 mm tall.
  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.
