This thread goes along with my post about [TAZ 5 PLA random clogging issues and a solution.](https://forum.lulzbot.com/t/taz-5-pla-random-clogging-issues-and-a-solution/1661/1) I needed to create a way to provide a serious amount of cooling for my TAZ 5 / Hexagon hotend. The little “squirrel cage” fan was just… cute. No offense to the Taz designers! I LOVE my machine 🙂 But seriously, that small fan was way too small, and it was actually really noisy. So, as all good do-it-yourselfers would do, I designed and printed my own along with a Filament Tube Retainer.

The Filament Tube Retainer is a modified version of [http://www.thingiverse.com/thing:766614](http://www.thingiverse.com/thing:766614) created by Wolfie, and the fan shroud is my original design.

The intent of the shroud is to provide as much air flow across the cooling fins right above the heater block in the hotend itself, while preventing any airflow across the heater block. I also wanted to provide some additional air flow across the entire filament feed assembly, but I wanted it to look and feel as if it were a stock item. The shroud itself went great, but I realized that I wanted to keep the filament tube retainer that I had (Wolfie’s design), plus I needed a way to anchor the top of fan shroud. Slight design change = win.

As promised, here is the link to the .stl files and the Cura profile I used to print this. They’re over at [Thingiverse](http://www.thingiverse.com/thing:783515)

Here’s some pictures of the shroud itself. I printed it using PLA. I figured I’d really get to see if the clearance around the hotend was enough if the PLA didn’t melt 🙂
