LTT water bottle hydration tube adapter cap

thingiverse

Made to fit a 10x13mm tube (13mm outer diameter, 1.5mm wall thickness), which fits into a Source hydration mouthpiece. This version just passes the tube through the cap, but I was also thinking of a version that uses two bits of tube to make the cap overall more water tight. I originally also had an attachment to the top piece that would bend the tube more gently, but my early trials were too fragile to actually function well. I've used this on my backpack that has a water bottle pouch, which happens to fit the LTT 40oz water bottle. I then run the tube over my shoulder and have it attached to the shoulder strap where I can access the mouthpiece for drinking. Note: this version might leak a bit of water if not held upright.
