I know there's Titan and Aero IDEX mods and carriages and whatnot flying around but has anyone designed improved part cooling for the original bigbox carriage?
I use a version of Greg's dual cooler that I modified to suit my single extruder. I had to make some mods with a file to get my design to fit. SpoonUnit designed one that fits better than mine though: http://www.thingiverse.com/thing:1869814
