Water filter plug or mini bottle

thingiverse

Used here as a drip-stop cap for a Sawyer water filter. Now I'm able to stash it inside my backpack without needing a plastic bag to catch the filtered water that spills out after treatment.\r\n\r\nThis also proves useful as a waterproof container for small amounts of whatever.\r\n\r\nRowbot3D's idea is fantastic, but the bottom is too shallow due to my filter having a protrusion for connecting a drinking straw. To avoid reworking the design, I used nearadyn's step file to create a model that fits my filter perfectly.
