2 Inch Arc Reactor for cake

2 Inch Arc Reactor for placing in a super hero cake. 3 5mm LEDs with 3 x 220 ohm resistor in parrallel to a 9V battery. White LEDs often have 3v forward voltage drop, so they need to be this way, rather than serial. 6 mm dowel is pushed into rear of cover to hold safely in cake. Drawn up quickly in Fusion 360 Print as oriented, with raft, no support, 20% infill. http://imgur.com/a/L5qxc
