Creating a Nintendo 64 Controller Switcher Box

Updated: Jun 7


So this one doesn't exactly focus entirely on 3D printing but it's definitely related!

A friend of mine has been a keen speed runner of Super Mario 64 for a few years now (you can check out some of his runs here) and he approached me a while back asking if I could make him a device that means he can swap controllers without having to unplug anything. After a quick bit of research, I discovered this was actually a really easy project to do and I did actually make one for him before I owned a 3D printer, however this was super messy and pretty amateur looking.

Fast forward 4 years, I found myself amidst a global pandemic and with a lot more free time on my hands. The perfect time to have another crack at this project.

I started off by first measuring the N64 female port to create holes to fit. I wanted to make sure I had these perfect before designing my enclosure for the switcher box.

After 3 quick revisions, I had a perfect fit

With the controller ports now fitting nice and snugly, I needed to design the entire enclosure for the switcher box. I went with a pretty simple shape as I wanted it to be easy and quick to 3d print.

The enclosure is made up of 2 parts, the main body and the base. These 2 parts connect using a pair of snaps that I designed into the base.

The prints came out great and needed very minimal supports as you can see below

Now it was time to assemble the extremely simple electronics. I took 2 N64 controller extensions cables and used hot glue to secure the female ports to the inside of the enclosure. I then cut and stripped back the wiring of the cables to expose the internal wires (Red +v, Black Ground, Green Data). After inserting the cable from the male N64 controller cable into the enclosure and securing with a little bit more hot glue, I soldered all the +v and ground cables together. This enables both ports to draw power from one controller port on the N64.

The final step was to add a simple toggle switch to allow switching of the active controller port. This is done by adding the male controller cables data line to the middle pin of the toggle switch and the female data lines to the outer pins. I crossed the wires over here so the direction of the toggle switch matched the active port. I then secure the ground and +v cabling in place with another helping of hot glue,

I then pressed the base into the main body of the enclosure and was finished with the project.
