Fits on a standard 20oz bottle (your 1 liter, 2 liter, 12oz., etc.). enjoy, or edit it and post a make I'd love to see other design.
Update12/31/2016
I learned a little bit of cad using onshape. So i redid my old design to be more robust and clean looking. the downnstem is larger the mouthpiece is larger... and yes you can put a lighter in the mouthpiece now...
the gg adapter is now a better size to accommodate a real 14mm bowl. im leaving the old one up for anyone who wants it(dont know why).
