This is a pour spout for Sigg / MSR bottles. It's based off a few old pour caps I remember my dad using when I was a kid.

Supports: only for the underneath of the flat base above the threads
Material: I printed with PLA and it came out great. Other materials will likey work.
Caution
If you are using this with fuel--like for a camping stove--be sure your material will not react with the liquid. I'm using standard liquid Coleman camping fuel, which doesn't react with PLA, and even then only attaching the spout when I need to pour something. Otherwise it has the supplied cap.
