Good eve all, I sat down last night and decided to start looking for a fan shroud that would encompass both the E3D and parts as PLA is printed. I found a lot of different flavors out there, but nothing that really sung to me. I then found a parts fan that I liked, but it was designed for another Hotend altogether and I decided to do a hack job. Yes, I was being lazy. The resultant fan shroud is located here: http://www.thingiverse.com/thing:289114 : and holds the original 20 mm fan for the E3D, and an additional 40 mm fan for part cooling. Here is the printed shroud the first time that I used Cura, which did not go well when removing all of the supports.... And once after I am done printing with it I will post up a finished product image. Jason Here is the side view of the shroud. All of the other images were too crap to put up. Will take more tomorrow.
As imaged above... it snapped the E3D shroud :/ I then went in and put up my own supports, and added some structure to the weaker areas of the main shroud: Everything just snapped right away, and the results are what you see in the above image where it is on the E3D. It works very well as I was able to do a 100 mm bridge test with very minimal droop in the first layer of the bridge. I could have eliminated even that by increasing my print speed from 60 to 80 mm/s, but I print slow and doubt that I will have need for a 100 mm span again. Of course... There are some droops in the main shroud, the part shroud needs to be clipped a bit on the feet to keep it away from the heating block, and I have to make the correct hex-nut location accessible instead of one that has no need for a side opening o.0
