Manifold Style Boot Dryer

Revision Block
April 17, 2017 - Initial Release
April 19, 2017 - Updated fastening locations to be in the main housing to reduce part footprint and reduce material consumption. Added STEP assembly to attached files.

Description
This is designed as a boot dryer to utilize 40mm equipment fans, which can typically be powered with 5VDC (USB), and would utilize 1" diameter corrugated hose.
I should be including updates to this design, and let me know about any feedback on improvements!
