About this model

A printable, wearable arc reactor based on the Mark I movie version. There are already some great arc reactors on here, but I wanted to take my own crack at it. -------------- Update: I increased the clearance of the top ring, should be easier to assemble now. Also added source files. Update: I uploaded the 9V battery holder you see in the pictures due to multiple requests, as a warning it is not an optimized part but a quick design to work with the switch I had on hand. I am sure there are better designs out there on Thingiverse if you look around.
