About this model

Current version of an arc reactor chest piece designed to go directly on your chest and held in place with skin latex and a non-toxic glue stick. The diffuser section is a stand in for diffuser acrylic, and the separator will be updated once I have the rest of the circuit components. Full build log for the prop will be added once I've got everything situated. But figured other folks might want a nice arc reactor in the meantime.
