Double Helix 810 Drip Tip

Double Helix 810 Drip Tip, With a large outside diameter at the bottom for strength and a bore that is larger at the bottom than the top, to function as an expansion chamber.
Has an internal double helix for strength as well as to reduce pop spatter and force vapor to travel further before it gets to your mouth.

This is the 810 version of my 510 Double Helix tip.

Update: Was inch scale, is now in mm. I didn't catch Inventor's revert to the default in the initial export.
