Summary

Quickly done for my nephew, who needed a stand to play his switch with a wired controller
(This controller requires a USB-A to USB-C adaptor, the stand had to be hight enough).

This stand can be taken to pieces (3 parts), and so easily carried.
Easy to print, without supports.

Edit: I've added an alternative central part.
The first one was quickly drawn to let my nephew use right now.
But, it's a bit delicate when unmounted and depending on the filament used, can break.
So, I've made the second one, stronger but bigger.
Choose which one is better for your needs.
