I wanted to create my own dock for the Nintendo Switch as all the ones out there are quite expensive. I created a simple design to accomplish this task with the only major cost being the USB-C hub. It can be used as a simple charging dock or you can plug in any compatible adapter for full functionality.
The dock does not use parts from the original switch dock nor use any spring mechanism. Because the adapter is lightly fit into the bottom, I recommend this dock only be used on a hard flat surface. The dock also doesn't obstruct the screen so you play while only charging.
My switch has a glass screen protector and recommend you have one too. I am unaware how overall fit is affected without screen protector and vinyl skin.
The hub is designed specifically for this 90-degree USB-C adapter:
