Holder for the Apple's magic trackpad 2 (type c / lightning) it levels the trackpad and raises the height to be comfortable for using beside a mechanical low profile keyboards (such as Keychronk series)
It is easy to put the trackpad in and out of the trackpad, when traveling with it. This is why only the right and the top corners have the “limiters”, also not having the wall on the left allows s it to sit snugly against the keyboard
The author marked this model as their own original creation.
