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: Shipped one-piece Magliner/cart lip mount (strongest). Optional M5 heat-set insert + nylon thumbscrew.

HOW IT WORKS
  Keeps the voltage testers on the cart instead of on an apple box. One pocket takes a Fluke T5 or T6 clamp-style tester, and two pen bores take Fluke 1AC-II and Klein NCVT-1P/2P/3P class non-contact testers.
  T5/T6 pocket
  Rectangular, 34 x 55 mm at the rim and 32 x 53 mm at the floor, 118 mm deep, for the T5's 30.5 x 51 mm body. The meter drops in bottom-end first with the display facing up and stands on the flat floor. The taper centres it, so it does not rattle. It stands about 73 mm above the deck, so you can grab it from any side, above everything else. It is the heaviest item, so it hangs lowest. Check your meter: with the leads clipped in the back holder it must be no more than about 31 x 52 mm across.
  Pen bores
  Each bore is 27 mm across for its top 60 mm, then narrows to 16 mm at the floor, 92 mm down. Any pen tester up to 26.5 mm across drops in at least 60 mm. A tester whose tip is 16 mm or less across stands on the floor. A 148 mm Fluke 1AC-II then tops out about 44 mm above the deck, and a 145 mm Klein NCVT-3P about 41 mm above it. The tester has to lift about 90 mm before it comes out, so bumps do not throw it. The pocket clip rides in an 8 mm keyway on the outboard side, so the tester always faces the same way and you can grab it blind. These figures come from published lengths and widths: measure your own tester, and expect it to sit higher if it is wider than 26.5 mm anywhere in its lower 60 mm.
  Grabbing
  The bore rims sit 12 mm below the deck, so about 55 mm of each pen stands clear. There is 15 mm between each pen and the mount block behind it and 18 mm between the pens, and the front is open, so you can pinch a pen from front and back, even in gloves.
  Each mouth has a 1.5 mm lead-in, and a drain sits at each bottom. Each pocket has a recessed label flat on the front collar. Everything that touches the testers is plain plastic.
  Numbers

  - Sticks out 59 mm from the cart side
  - Hangs 133 mm below the deck (the bottom of the T5 pocket; the pen bores end 107 mm below)
  - Needs 45 mm of flat cart side below the lip for the back plate. Below that, the part stands 4 mm off the cart
  - Overall 77 x 144 x 175 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.
