Improved hotend duct for Lulzbot Taz5. MUCH better cooling of the hotend. Cured PLA filament jams (grinding) as soon as I installed it. Uses a 25x25x10mm fan with a duct that surrounds the hotend instead of the small blower that is stock. Uses the same 2mm mounting screw as the stock fan.

This duct and fan keeps the upper section of the hotend cool and keeps the filament cool before it feeds into the heated section. Works like a champ!

We were having quite of bit of trouble with filament
