This model fits slim mice and keyboards, i.e. magic keyboard (horizontal or vertical orientation supported) and mouse (horizontal only) from apple, where both can charge on the dock itself.

Keyboard slot currently about 1.2cm wide (just big enough for the magic keyboard, though my logitech k750 fits this as well)

Mouse slot is about 2cm wide, and tall enough to rest on the bumper of a magic mouse when facing outward.

I made this 2 in 1 because I often run out of desk space, and frequently switch between my gaming keyboard and my apple one.

Open to suggestions on sizes.

nits; the mouse slot wall is quite thin at the tallest point, so room for improvement there.

Also the walls are on the thin side, and would not support a gaming keyboard (full metal) without worrying about it breaking, especially in a vertical position.
