Stack Frame for Clear-Lid Cases (all sizes) - Dock (swap between mounts)
======================================================================

What it holds: Stack two clear-lid cases for storage or the truck. The frame straddles the lower case's DOCK tongue and locates the upper case by its bottom step.

PRINT SETTINGS
  Filament:  PETG
  Walls:     5
  Infill:    35% gyroid
  Orientation: the files are already oriented for printing. Put them on the plate as they load;
               don't rotate them.

HOW IT MOUNTS
  DOCK (SWAP BETWEEN MOUNTS)
    Swappable: print the holder (it has a dovetail tongue on the back) and ONE adapter for the thing you
    want to hang it on. Drop the holder into the adapter from above until it clicks; press the release pad
    and lift to take it off. Move it between a cart lip, a ToughBuilt bar, a tube, a panel and so on by
    printing more adapters. Wide holders have two tongues 60 mm apart: print one adapter per tongue.
    Lock screw (every adapter): 1 x M5 short heat-set insert + 1 x M5 x 25 knurled thumbscrew (DIN 464) in the 45-degree lock boss. Optional on a bench, use it on moving carts and lift gates.

  WHICH ADAPTER TO PRINT (all in the adapters folder; print only the one for your carrier)

    Notes for this holder: For the swappable (tongue-back) cases: print the frame that matches your case size. It sits on the closed lower lid, straddles the lower case's tongue(s) and locates the upper case by its bottom step. Prints upright, no supports.

HOW IT WORKS
  The DOCK tongue on each case rises 10.5 mm above the lid, so cases cannot sit straight on each other. This frame sits on a closed lid, straddles the lower case's tongue(s) and lifts the next case 11.3 mm. The upper case's 2 x 1.4 mm bottom step drops into the frame's top band, so the stack does not slide. One file per case size (2x1, 3x1, 4x1, 3x2, 4x2), 22-43 g. Print upright, any PETG, no supports.
  This is for storage and transport, not for a moving cart: on the cart each case hangs on its own adapter.

OTHER MOUNTS
  The same holder also comes Mountless (desk, shelf, case or screw to a panel). Pick the mount on the site: https://cart-tools.sdos-placeholder.workers.dev/#case-cf-stack-frame-2x1

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.
