* frame width has been reduced in order to leave more space and have
  sunken buttons somewhat accessible
* the cutout for neutrik mounts has been reduced and moved into the
  holes themselves, to do this more modularly and restore some support

     * Some levers don't have enough clearance in the case.
     * Buttons with traditional quick connects are a *very* tight fit, you will probably need to bend pins.
 * The PCB mount position was very tight on the buttons panel; it will probably have to be moved.
-* Support for the top plate was removed from the frame due to overhang issues, and now the top plate can bow slightly

 These issues may be fixed in the future; see `TODO.md` for details.

   adding 5mm to the frame should leave a couple mm for support to get added back
 * PCB mount on `top-panel-dir_arc-plus-w-30mm-plus-one-with-mount.scad` doesn't leave room for a USB cable on the right
