Phone holder for Logitech G815 keyboard

Coming from the Logitech G910 keyboard, the thing I'm missing the most (the only thing I'm missing TBH) is the phone holder. I got used to it and now I find myself trying to place my phone in a non existent holder.

So I made a very very simple phone holder that fits the Logitech G815/G915 keyboards (or, more in general, all the 10mm thick keyboards)

It's designed to be printed with one of the sides down (placed vertically as a tower) so that it won't require supports.
