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 fork 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 upside down, fork top and block top on the bed, no supports. ~236 g.

HOW IT WORKS
  The impact driver hangs by its head on a flat fork, bit out and battery down, the way you grab it. The trigger faces the open mouth, so the holster can never press it.
  It clicks: two springy fingers are cut into the fork. Their 2.2 mm bumps snap in front of the grip once it is seated. Pull-out is about 50-55 N, about three times the swerve load of an 18 V impact with a 5 Ah pack.
  The direction switch stays free: the top of each finger is notched 9 mm deep right where the forward/reverse rocker sits, just under the head. That leaves 5 mm of room beside the grip, so the rocker never gets pushed to centre and the tool always seats. Print the matching band coupon (included) first to check on your tool.
  Spare bits: four 1/4 in hex sockets at the prong tips take 25 mm insert bits or 50 mm power bits. A small crush rib in each socket holds the bit on kerbs.
  Size: the slot is 40 mm, for grips 38-39 mm wide and up to 54 mm deep just under the head. The head may reach up to 22 mm behind the grip, which fits impact drivers and some compact drills. For a drill/driver or hammer drill with more motor behind the grip, use the 18 V drill version. The fork sticks out 98 mm from the holder back.
  Weight limit: packs up to HO 8 Ah. Do not use 12 Ah packs: a big tool with a 12 Ah pack goes over the twin DOCK rating.
  Quiet option: the tool can lift a little on hard bumps and tap back down. It cannot come out, but two strips of 2 mm TPU or felt on the fork top keep it quiet.
  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.

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.
