Dynavap M 14MM Adapter (With hole-finding thumb groove!)

thingiverse

(18MM Coming Soon!) I created an adapter one day and invested some time putting this together. I made it a bit thicker so you have an easier time finding the thumb area. If you don't want to use a choke, simply spin the dynavap away from the hole. This is snug (but not too tight) on my Dynavap M. Depending on tolerances yours might be more or less snug. I printed about ten of these before settling into the snugness that worked for me. If yours ends up too tight or loose, adjust your extrusion multiplier a little and it should be enough to offset it comfortably. No supports are needed. The inside flanges inward via chamfers. Print it with the bong-socket-side down.
