135 degrees angle tube for helmet hydration system

thingiverse

I bought a USWE Ranger 4 hydration backpack for Enduro riding but couldn't use the handsfree kit in my Alpinestars SM8 helmet.I wanted to use the tube fitting that is included in the helmet, so the tube can barely be seen on the outside.So i had to come up with a solution for the sharp angle the mouthpiece had to make so the bite valve would be directly in front of my mouth. After a few design flawes the tube works perfect. I would suggest to use a bit of electical tape or flexible glue (like B7000) to securely fix the bite valve to the tube.
