This is a little plug for the SpaceNavigator to use USB C breakout boards, and convert it to USB C.
To install, first unscrew the 3 screws on the bottom, underneath the rubber ring. Pull the base assy off too, that holds the cable in place. The top assembly should come off.

Next, unscrew the bottom PCB by the two screws on each corner.

Unplug the USB cable on the other side of the PCB, cut the cable, pull out the rubber plug that secures it to the chassis, push the 3D printed part into the hole. Thread the wire through the USB port, solder it to the USB breakout board, glue the port in place, and do all the steps in reverse to assemble again.
