Arc Reactor Technical Drawing

A technical drawing of Tony Stark's minaturized arc reactor. Done old-school with a technical drawing set and a protractor. All measurements are prescise, so it's perfect for aiding in the construction of an accurate replica. ( thats what i drew it for) If anyone creates a model using this blueprint I would love to see it!

I've gotten a lot of suggestions for metric values so, here ya go!
Metric Values:
3"= 76.2mm
4/10"= 10.16mm
