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 (strongest). The boot sits 7.5 mm closer to the cart and 8 mm higher than on the DOCK adapter; back plate bears on the cart side. Optional M5 heat-set insert + M5 thumbscrew clamps the lip. Prints upright like the DOCK version; turn on support ON THE BUILD PLATE ONLY: it only lands under the lip block's inner flange (the rest needs none). ~315 g. Print 2 of the shim that fits your pack (RG_shim_XC or RG_shim_HO) and use the 25 mm strap.

HOW IT WORKS
  The gun stands on its battery, as it does on a bench, in a boot 144 x 88 mm inside. Only the pack and tool foot touch the print. The nozzle points along the cart, 127 mm from the nearest printed surface.
  It cannot hop out:

  - Two drop-in end shims take up the slack for your pack size. RG_shim_XC is for CP and XC 5 Ah packs; its cheeks also take up the front-back play, leaving about 1 mm. RG_shim_HO is for HO 6/8 Ah and Forge 8 Ah packs. Print two of the one you need.
  - A 25 mm hook-and-loop strap is required. Thread it through the two back-wall slots and cinch it round the tool just above the pack, so the foot cannot lift past it.
  - The end walls are 54 mm tall. The front wall is lower with 45 deg shoulders. Finger scoops in the ends (and in the shims) let you grab the pack, and 5 floor slots drain the boot.
  Heat safety: the wall carries the raised words COOL BEFORE STOWING and NOZZLE IN FREE AIR. PETG softens at about 80 C, so ASA or PC is better. Never stow the gun nozzle-down, and keep other holders 150 mm clear of the nozzle end.
  You need: 2 DOCK adapters with thumbscrew locks, one 400 x 25 mm hook-and-loop strap, 2 shims.
  Mounting (DOCK system): the back carries two DOCK tongues 60 mm apart (use two adapters set with the 60 mm spacing gauge). Drop it into DOCK carrier adapters (Magliner / Backstage lip, ToughBuilt bar, round or square tube, T-slot; all in the DOCK system listing) and it clicks in. To take it off, push the release pad with your thumb and lift. Fit the adapter's M5 lock thumbscrews (required): this holds a heavy tool well out from the cart.

OTHER MOUNTS

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.
