Osprey Hydration Bladder Dryer

A simple print that solves an annoying problem: hydration bladders that never dry out and end up mouldy.

This stand screws into the filler opening of Osprey Hydraulics reservoirs (the wide twist-lock cap shown in the photos) and holds the bladder open with two arms. Water drains freely, air circulates through the propped-open reservoir, and the interior actually dries instead of sitting damp and sealed

Fit note: designed around the Osprey wide-mouth twist cap. Thread sizes vary across brands and generations, so check against your reservoir before a long print. Happy to hear about fitment on other Osprey models in the comments.
