For my 8BitDo Ultimate 2C Wired Controller I made a stand that also has the option to wind up the cable and secure it.

I wanted a solution that held my controller and also provided me with a way to neatly tuck away the cable (since it's the wired variant).

This model constist of 3 parts;

1. The Base stand
2. Base side cable holder
3. Top part of the cable holder (With the notches)

You can print the stand on it's own if you feel you don't have a need for the cable holder.
You just need some appropriate glue if you do plan on using the cable holder. The parts have a little notch to line them up correctly.

I know it fits with this controller, I do not know if it fits with older versions of the 8BitDo controller. I'm pretty sure there is no difference between the wired and wireless version but that is also not something I am sure about.
