25MM fan to airline hose adaptor

While checking out the G+ Makibox user group, I saw a discussion about adding a fan to the hot end https://plus.google.com/103982631119479761813/posts/gMcAYUUjnyy. Another user had designed a system to hang a fan on the hot end

I kind of like the idea of using an aquarium air pump a little better, but I get why some users would want to use a board-powered fan (one less AC plug for starters). On the other hand, having the fan mounted on the print head does add some weight (probably nothing worth worrying about, but I've read that any extra mass can cause more backlash), so I decided to design a template to add a nozzle to the fan.

UPDATE! So, I've gotten some good feedback from a few people on the G+ page pointing out this thing CANNOT POSSIBLY WORK! I'm not an engineer, so I'm going to nod my head like I understand, but the gist I get is that a normal CPU-style fan won't push air hard enough to go through the tiny airline hose out let. Oh well.
