Active humidor humidifier

This is an active/passive humidifier for a humidor. you can add a 30mm fan to it to make it work for larger humidors and provide circulation. I am building this as an intermediate step to a fully automated humidor.

Instructions:
1. print box.
2. obtain *WET* floral foam. needs to be the wet kind. http://a.co/b50odSu
3. put in the box.
4. close the box.
5. buy Propylene Glycol. http://a.co/eQmdijI
6. mix Propylene Glycol 50% with distilled water.
7. drip into box until saturated but not dripping.
8. add 30mm fan (optional)
