Vape Pipe

I've long thought that a vape in the shape of a tobacco pipe would be cool, as the form factor of a vape has little to do with the function short of being a container. I've looked around for a while for a vape that is in the shape of a pipe, but could not find one for a reasonable price, and have yet to find one locally in my small town. So here is what I have designed. It is designed around the 18350 rechargeable lithium battery (slightly more than half the height, same diameter, around half the charge capacity).

This is a work in progress, as it does not have a receiving slot for a lithium battery charger, and no easy way to mount a tank to the stem. I am leaning towards a spark fun lithium battery usb charger circuit: https://www.sparkfun.com/products/10217 and a 14mm diameter run of the mill tank.

Again, this is a work in progress. I welcome any recommendations, or even requests in the design. When it is at a reasonable state of completion, I will release the openscad file and change the cc license to public domain.

Thanks for any feedback.
