CNOC to 8mm Hose Adapter

This adapter connects a 8mm hose to a standard soda bottle. I designed this to mate a CNOC water bladder to a piece of 8mm diameter silicone hose which in turn can mate to a Sawyer water filter. This creates a gravity filtration system.

Print it with supports to base plate only with part standing on the 8mm hose pipe. Otherwise you'll have a hard time removing supports...

Update: Added a reinforced version after a comment that the part broke easily. Expect slighly reduced water flow since the diameter got reduced. Shouldn't be an issue though since the limiting factor is the Sawyer filter in any case.
