Clip to keep open a water bladder and attach it to a cord for drying. Without clip there is no easy way to hook a bladder to a clothes line with it open and facing up, causing it to take 1+ weeks to dry.
Fast print with no supports needed. Fits up to 8mm carabiners. Designed for Platypus and Nathan brand bladders, but may work for others. Not needed for Camelbak brand as they already have a drying hook on the top.
