standalone frame, with tweaks to the frame as a consequence

* 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

@@ -45,13 +45,10 @@ What you'll need beyond these objects:
 
 This is a living repository, and as such, there are likely issues with the objects, known or otherwise. Be aware:
 
-* The top panel is 5mm tall and doesn't have an inset; snap-in buttons likely do not fit.
 * A composition error made the frame 5mm shorter than intended and wasn't noticed until I printed everything:
     * 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
-  with pressure; a new solution needs to be found.
 
 These issues may be fixed in the future; see `TODO.md` for details.

@@ -7,12 +7,8 @@ Notes for "next time".
 * I need at least 5mm, maybe 10mm, more height, to fit some of my levers like the Nobi Bullet
     * I couldn't even fit a JLF without the compensations in v1 on the bottom panel
     * I had to bend the pins a bit on Crown SDB-202s, too
-* Top plates are 1-2mm too thick for snap-ins, maybe have a variant with a couple shaved off like with the bottom plate
-  workaround
 * The plates bow a bit on the top when pressure is applied, because there's no support from the frame up there ---
   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
   hand side
-* The panels' connection points could probably be a bit thinner to accommodate more bolts. A 20mm bolt barely clears the
-  two panels and I don't like that kind of bolt connection.
 * Engraving some cosmetic stuff? Or maybe a place to mount other plates?
