I'm a tinkerer, I like making things.
So when I saw that I could buy a fan for Nanaya's muzzle or build one, I picked the difficult route instead.
I bought a small 12v fan, a 9v snap connector and a 9 volt battery.
I simply twisted and connected the correlating wires to each other and wrapped up the connecting pieces with electrical tape. I tried it out and it works!

The fan is incredibly quiet and the force is splendid and just what I'll need to stop from sweating to death. Later, I'll be wrapping the two wires together in more electrical tape and making a custom case for the battery.

Oh, and I ran the battery to see how much 9v will last me, and I got about 3 hours of sturdy air blowing. I'm happy.

Entire thing cost me.. twelve bucks? Yeah.
Thanks for readin'!
