Audio Switch case

box for the audio switcher (https://de.aliexpress.com/item/Audio-Switching-Board-3-5mm-A-B-Audio-Input-Block-Optional-Select-Output-Type-Module/32674273971.html)

with holes for magnets 7x3 mm
3mm screws will fit nicely to hold bottom and top together.

- Added a schmall version of the case for the new smaller PCB layout that is sold on Aliexpress. This is a glue-only version.

- Added V3 (big version) with fixed hole and slightly more depth for the magnet. V2 is the original one.
