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: Default: one piece with the Backstage/Magliner cart-lip mount, strongest. Prints standing on its end face, no supports; M5 heat-set insert + thumbscrew lock on the lip. Print the left AND right saddle (one each end of the strip).

HOW IT WORKS
  Turns the side of the cart into a charging station, with the power strip off the shelf and out of spills.
  Two saddles hold one strip: a left one and a right one (mirror images), each on its own mount block. Each saddle is a C-channel that wraps the ends of the strip, with the outlets facing out from the cart.
  What fits (Standard, inside 57 x 44 mm)

  - common 6-outlet surge bars 50-56.5 mm tall and up to 44 mm thick (the popular ~54 x 41.5 mm size)
  - Strips of any length: you slide the two saddles along the lip to suit
  - Measure your strip across the outlet face (the height when it hangs) and front to back. Three sizes are in the set; pick the one whose range covers your strip
  Fitting it
  1. Press an M5 short heat-set insert into the boss on each saddle's roof (and, if you want, into the mount flange).
  2. Put the left saddle on the lip and slide one end of the strip into it until it meets the end stop.
  3. Slide the right saddle along the lip onto the other end of the strip. The strip is now boxed in on every side.
  4. Turn a nylon-tipped M5 x 25 thumbscrew down through each roof boss onto the top edge of the strip. It clamps the strip onto the saddle floor, so the saddles cannot creep along it. One hand, no tools.
  What it covers: nothing crosses the outlet face. The front lips are 6 mm tall at the top and bottom and only 12 mm long, over the very end of the strip, which leaves a 45 mm window between them. So the face needs only about 12 mm free at each end; a plug head or face switch closer than that to the end of the strip may touch a lip. The end stop is two tabs (top and bottom), so the cord leaves through the open middle and a switch on the strip end stays reachable. The lips have a 45 deg lead-in.
  On a moving cart: the strip cannot lift, tip out or slide, because it is boxed in by both saddles and clamped by the roof thumbscrews. The M5 thumbscrews in the mount flanges stop the saddles lifting on a lift-gate drop.
  Numbers

  - Sticks out 61 mm from the cart side
  - Hangs 66 mm below the deck (the block top stands 42 mm above it, as on every part in the range)
  - Needs 45 mm of flat cart side below the lip for the back plate
  - Plugs add their own length (usually 30-60 mm) in front of the strip
  - The clamp boss stands 10 mm above the deck (the thumbscrew head about 10-20 mm more), outside the cart edge
  - Opening between the lips: 45 mm
  - Each part 79 x 34 x 108 mm (out x along the cart x tall)

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.
