Part fan for a Press with the E3Dv6 Bowden mod

I replaced my hotend with the E3Dv6 and did the PEI heated bed upgrade from the classic instructions from MacGyverX thread. The Press is no longer my main printer but I'd still like to get good parts out of it. I'm printing on it now with PLA for the first time and it looks like it could do a good job if I added a part fan.

Doing the design from scratch is a pretty daunting task. I'm looking at the one on my i3 MK2 and it seems like maybe a variation on that would fit. Has anyone else built something to fit in this kind of space? I'm not sure exactly what'll be involved.
