I wanted a charging dock similar to my Nyko charging docks for my other systems. I decided not to copy the Nyko aesthetic completely, but I did borrow the idea of a modular system which allows you to put several controllers in a line by connecting blocks. You can see from the photos that the blocks connect via hooks in the front, and there is a front piece which can be used to cover the hooks up on the first block.
I also wanted to keep it simple, so I just put a channel underneath to allow cables to be run through, with a channel running up to run the cable up to the controller. I think it looks pretty clean, but if a talented designer out there wants to modify it to look even better, please do so!
I printed mine without supports, but if your printer isn't great at bridging even small gaps, I would put supports from build plate only. The only spots on this model that bridge (or need supports if you don't want to bridge) are the hook receivers on the back of the pieces. I'm sure this could also be improved, but it prints well enough on my machine, so I left it as is.
I also put rubber feet on the bottom of mine to keep it from slipping around, and that is definitely recommended.
