Perma-Proto sidex Feather Box

This is a variation of the Adafruit Feather Box, which we love.

We needed to put a PermaProto (1/2 sized) in the box, so we adjusted the Fusion 360 file.

Contact me for the F3d file if you want it - we are feeding this back to Adafruit and I'd like to get their input before sharing it here.
