NS14 SG13 Dynavap M Bong Adapter

Made an adapter for the Dynavap M (All versions should fit) for use with a small bong cut (size 14 mm).
I printed it in TPUto get the best fit. It should also work with any other material, but then u might have to play around with the horizontal expansion setting or increase the size by a few percent. If needed, I can make a version without the inner gripping ring, for easier use with play, but I like the "clipping" feeling when it locks in place, so consider a not-so-flexible TPU as preferable.
The handle is intended to double as a cover for the hole, if not tight enough, just add a bit of cotton, maybe a clean eartip?

Always be safe and remove stringing! 

You don't wanna smoke the plastic there :)
Enjoy!
