3D Printable Arc Reactor

A printable, wearable arc reactor based on the Mark I movie version.

Assembly Instructions:

• Required parts: 5 M3x10 screws and nuts, 14 White 5mm LEDs, 10 Blue 5mm LEDs (optional), Resistors (depending on your configuration).
• Print the crystal in clear PLA and the other parts in a dark color (metal or black is best).
• For best results, print the crystal with a low rectilinear infill and no more than two shells.
• Assemble everything except the base. Optionally, apply aluminum tape on surfaces you don't want to be translucent.
• Place white LEDs in holes not covered by the top piece (10 around the perimeter and four in the center). Optionally, put blue LEDs in the remaining holes for a nice bluish glow.
• Sand LEDs before wiring for a more diffused glow.
• LED wiring will depend on your power source. Recommended 9V battery with eight parallel runs of 3 LEDs in series with a 68 Ohm resistor.
• Cut a hole in a t-shirt just big enough to fit the crystal, pin the edge of the cloth in the groove between top and base parts, and secure with screws.
• Attach a belt using the slots in the base to ensure the arc reactor stays in place. Run a wire under your clothes to your power supply since there’s no room for a battery in the reactor itself.

Enjoy! P.S. I strongly recommend not trying to get on a plane with this on.
