CamelBak Hose Quick Release

thingiverse

This is an air-tight copy of the CamelBak quick release system. I'm using a 4x15mm spring that's press-fit but you may need a little CA glue to keep it secured. I print this with regular non-tree supports set to auto, and it takes a little effort but getting the supports out isn't too difficult. I have a small file I use to smooth out the opening to make sure the button works well.
