UPDATE: Upgrade, new electronics calls for new parts. This one also has printed rubber grips. Looks, works, and feels MUCH nicer. People kept telling me my ecig looked light a lightsaber, that along with a request to make some lightsaber parts inspired me to go that extra mile and print some parts to make it REALLY look like one. Notice how I worked my trademark MMM in. It's three parts that slide onto the existing body and hold with friction, but I did glue the grip part for stability. I'm not even that big of a SW fan, but carrying a lightsaber around in my pocket was too nerdy to resist.
