Update: I added a piece to cover the batteries. And I also added new option for the electronics cover to allow for 10 LEDs and 3 on the bridge pieces. Just in case you wanted to make a more realistic one that flashes. Requested by fma :).
This is a 3D printed Flux Capacitor with the option of putting electronics inside to make it light up with LEDs. This is meant to be a fun printing/electronics project and not meant to be a hyper-realistic prop. So have fun with it! :)
