Powered Bottle Dryer

thingiverse

I'm just leaving my water bottles out overnight, they still remain wet in the morning. But with this setup, they're completely dry within an hour or two. This requires a trusty 5015 squirrel cage fan to get the job done. I used a 12v spare from one of my printers that I had lying around and attached it with some M3 hardware. An extra 12v wall wart was all I needed to finish the project off. You might be able to use a 5v version instead and power it with a phone charger, although it would take a bit longer to dry your water bottles completely.
