====================

Flat panels: plywood cart sides and shelves, tool-chest or cabinet sides, walls. A_SCREW_panel takes 3 x #8 / M4 countersunk wood or machine screws (or M4 rivnuts); A_SCREW_panel_M5 takes 3 x M5 countersunk through-bolts or M5 rivnuts. Each hole has a back counterbore for a rivnut flange.

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.

WHAT IT IS
  A dock adapter. It holds the receiver that any swappable holder on the site clicks into: print the
  holder's Dock (swap between mounts) version, fix this adapter to your carrier, and drop the holder in
  from above until it clicks. Press the release pad and lift to take it off.
  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.
