Multiple device charging stand

This thing organizes devices for charging, taking them off the countertop, and saving space. It encloses the Anker charger, with taller slots for tablets, and a wide slot for the Nintendo Switch.

I was inspired by the basic idea and vibe of https://www.thingiverse.com/thing:2357789, but wrong charger, didn't handle the devices it needed to, etc, so I designed this one from scratch for my spouse (hence the heart).

Requirements were that it had to handle a 7" tablet, a Kindle, a good-sized phone, and the Nintendo Switch, which is quite a bit wider than all the others. The higher columns support the tall devices well. There's currently one extra slot.
