After adjusting my search terms a bit I managed to find one that is not dependent on the R2 carriage brackets/system. When searching for E3D cooler or similar you will find a fang like cooler such as https://www.thingiverse.com/thing:2175956 which mounts onto the E3D 30mm fan. There are various remixes for dual radial fans, axial fans, dual extruder systems, etc.
If you are printing this cooler without a parts cooling fan you can use a house fan to blow on the part on medium speed. I've done this and the part came out great. This only stands true if your FT5 is dialed in though.
