I tried to find a cooler I liked but nothing seemed to work as I liked, most seem to blow air at the nozzle or just in a small area around it resulting in poor part cooling.

So I made mine from scratch using the two above designs as inspiration and it seems to work great.

The main difference you'll notice when you look at the outlet at the bottom, is that it only blows downwards on the part, this has transformed printing parts with steep slopes from a sorry looking mess to looking practically perfect.
