This thing was made with Tinkercad. Edit it online https://tinkercad.com/things/8kTGMZVx9Y7 I added this fan to help keep the PCB from heating up .

Instructions

I cut the fan out of an old laptop .When I realized that it ran on 5 volts I built the simple L7805 voltage regulator you see next to it . I used original screws and spacers.I hot glued fan to top of mount.
