E3D with Titan Extruder Cooling Fan and Part Fan

thingiverse

I've been searching for a part cooling fan that fits my setup and after countless iterations, I decided to build my own instead of giving up. I found a great cooling fan mount for the E3D Heatsink on Thingiverse (https://www.thingiverse.com/thing:514141) and used it during the process of designing my own. I made several upgrades to the heat sink fan mount, starting with extending its length and removing the angle that was there initially. By removing the angle, printing without supports became much easier. Additionally, I added a few fins that keep the unit aligned with respect to the heat sink at all times. Next, I designed a part cooling unit that can hold a blower fan (https://www.amazon.co.uk/gp/product/B071XSLTQY/ref=oh_aui_detailpage_o02_s00?ie=UTF8&psc=1). This component attaches easily to the heat sink fan mount and aligns perfectly with the Titan extruder cover. Looking at the STL pictures, you'll see the correct orientation for printing. With these orientations in place, the only support needed is for the part fan air flow path. Please feel free to use this design and thanks go out to SCHMIDDIM (https://www.thingiverse.com/schmiddim/about) for providing me with a great starting point. UPDATE: It's been pointed out that this unit may inadvertently cause cooling issues on the hotend. The suggested solution is to use a silicone sock, but after running a quick test in Octoprint to monitor temperature fluctuations, I found no problems at all. While a sock might still be a good idea for some users, my cooling unit does not need one. Here's a link to the temperature monitor results: http://i.imgur.com/WLo5to7.png
