Hydration Bladder Dryer

thingiverse

Add a 5-volt blower, a reliable power source, and a few screws to this device, and you'll be able to quickly dry out the bladder from a hydration pack (like a CamelBak) for storage purposes. If you've ever left water in one, even just a little bit, for more than a week or so, you already know what a tedious task it is to clean up before using it again. This design grew out of my frustration trying to position the blower with clothespins or chip clips and hold the hydration bladder open to get it dry. It was also motivated by a desire not to have the hydration bladder hanging in an inconvenient place for several days just to be sure it was completely dry. Note: The middle section of the "chimney" tube (the one that looks like a stepped box) can be printed multiple times for longer or taller bladders. Two of them, stacked, is probably enough for most full-size/100-oz/3-liter bladders.

The ones I used were just extras from previous projects so I don't have any specific source or part number for them.
