Take a look at the new and improved version: https://www.thingiverse.com/thing:2496634 Beware - Design flaw alert: attaching the shroud with a rubber band proved to be a questionable decision. Rubber bands inevitably dry out and break over time. To cut a long story short, I started a lengthy print, headed off to work, came back, and found my printer jammed still trying to print. The rubber band had snapped, causing the fan to fall off, lower shroud duct melted right through, cold end heated up, and a glob of molten filament formed on top just under the coupler. I was forced to disassemble the entire extruder and replace the nozzle to get it working again. Replace rubber bands frequently or use tie-wraps. This attempt at better cooling has some benefits. You'll gain a slight increase in build volume because the fan is tucked in under the spider. To keep things secure, you can hook a rubber band around the original mount.
