FreeDeck Case for threaded inserts

Simple remix of https://www.thingiverse.com/thing:4511644 to make the screw holes wider for accepting threaded inserts.

The threaded inserts I am using are McMaster-Carr #94459A130 4.7x4.3mm inserts which are a bit smaller than the common ones you can pick up on Amazon.
