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 (the shipped part). Optional M5 heat-set insert + M5 thumbscrew lip clamp. Prints upside down (rims + block top on the bed), no supports.

HOW IT WORKS
  Holds a hardboard clipboard (standard letter, 229 mm / 9 in wide) or a folder up to 15 mm thick and 230 mm wide upright, standing on its short edge between two closed end walls. Not for storage clipboards. Best on the top shelf or the cart end.
  Fits: Backstage Equipment and Magliner-style carts with a 3.4 mm upright shelf lip at least 16 mm tall. The part drops onto the lip through a 3.7 mm slot (0.3 mm clearance), 26.6 mm deep with a round end, with 0.5 mm chamfers at both slot ends.
  Two 40 mm cradles, 240 mm overall (232 mm between the closed end walls), 16 mm wide channel, 90 mm deep, 45 degree V floor with a 5 mm drain in each cradle. Between the two cradles the plate only reaches 40 mm down. Needs a print bed of at least 245 mm. Size 47 x 240 x 103 mm.
  On the cart: sticks out 29 mm from the cart side, hangs 61 mm below the deck, and needs a flat cart side 56 mm deep below the lip for the back plate to bear on.
  Retention: held by gravity unless you fit the M5 thumbscrew. Press an M5 short heat-set insert into the two holes on the shelf-side face (6.4 mm x 9 mm deep) and use a nylon-tipped M5 thumbscrew: it clamps the lip against the outer wall, so the part cannot lift off on a bump, slide along the lip or rattle.

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.
