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 (shipped part, strongest). Hangs by gravity; optional M5 heat-set insert + thumbscrew clamps the lip. Prints upside down (rims on the bed), no supports. ~191 g.

HOW IT WORKS
  Holds 8 paint pens or Sharpies (uni Paint PX-20, Sharpie oil-based paint, Sharpie fine/Pro) in two staggered rows of 4. Store them cap-up; lay paint pens flat for long storage.
  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.
  8 x 16.5 mm pockets, 55 mm deep, with funnel floors and 5 mm dust holes. A back plate bears flat on the cart side. Size 66 x 94 x 65 mm.
  On the cart: sticks out 48 mm from the cart side, hangs 23 mm below the deck, and needs a flat cart side 23 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 one hole 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.
