There is a compact version version via this link available
***** Update 12.06.2023*************
I recently bought a protective cover for my Kiox 300. With this cover the Kiox doesn't fit anymore into the first version of the wall mount. I've redesigned the wallmount and added a additional version for a Kiox 300 with a protective cover.
Now there are two files available. One version for “without a protective cover” and one “with a protective cover”.

A small remix of PuNk-FX “Bosch Kiox 300 Wandhalterung (Wall mount)” - https://www.thingiverse.com/thing:5445846.
Added a hook to hang a keyring (like https://www.thingiverse.com/thing:4843474).
Hope you can make a use of it!
