@ -45,7 +45,6 @@ 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.

@ -7,8 +7,6 @@ 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
