ZMK dongle case with switch and keycap slots

ZMK Dongle case for the AE kit (can't link to the product page here directly, but if you search “ZMK dongle” it should show up), which already comes with a case that this one is replacing. That kit also comes with a magnet and a metal piece which shall attach here. Keys are non-functional and are meant to be accessories/decorative pieces or at most as switch/keycap testers.

Note: everything is supposed to be a tight fit (including the magnet), so neither glue nor screw shall be required. Also goes without saying, but switches and keycaps are not included, feel free to provide them yourself with your preference.
