Sigg / MSR Pour Spout

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. 

Features

• Separate air intake and liquid exit holes
• Universal fit for Sigg / MSR bottles 

There are two variants:

V1:

• Wider head (10mm)
• Wider inner exit spout  (6mm diameter)
• Wider inner air intake spout  (4mm diameter)
• Beveled pour tip
• Small ring

V2:

• Narrower head (7mm)
• Narrower inner exit spout  (3mm diameter)
• Narrower inner air intake spout (3mm diameter)
• Flat pour tip
• Larger ring

Print settings

• Infill: 60%
• 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.
• Recommend using a rubber O-ring for a proper seal
