For whatever reason, pballerss' fang cooler for Titan Aero + Volcano did not fit either the space for attachment to my Aero's aluminum extruder cooling plate, or match the location and height of my hot end. I've used his basic design for attaching to the Aero, but made a ring type cooler that is large enough to go around the Volcano heating block (whichever way it's oriented).
The before/after photos show some improvement. Quality of prints is still comically bad, since I'm just learning to print with a 1mm nozzle. The layers are 0.5mm.
