Powered Bottle Dryer

Just leaving my water bottles out overnight, they would still be wet in the morning. With this, they're dry in an hour or two.

This requires a 5015 squirrel cage fan. I used a 12v spare of one I use on my printer and attached it with m3 hardware. An extra 12v wall wart finished the job. You might be able to use a 5v version and use a phone charger for power, although it would be slower.
