Just printed 2 for my R1 Plus and the fan ducts ended up pointing right at the nozzle and causing the temps to drop and the hot end is having problems keeping up.

Nice design Ethan. I made one and it looks great. Went together smooth and ZERO sanding. Thanks for sharing!

Hey Ethan, On my printer, the extruder fan is too close to the front of the carriage to mount the front fan. I've see picture of people turning it 90 degrees but can't figure out how to mount it. Did you have to do something with yours to get it to fit?

Here's an example of what it looks like stock: http://i.imgur.com/Ji8gjqD.jpg

It seems you have an older model of hot end. The newer models have the hot end fan on the left side of the hot end, and not in front of it. Sadly this design won't work in your case. I have no experience with that style of hot end. Best of luck and happy printing.

Printed this with my Creator Pro, came out perfectly as my Robo3D is down, waiting on a fuse. What size screws are recommended for the duct?

My problems that the fan wire is too short

Great model. printed one and have it mounted on the back side. Very little sanding required. Printing one for the front now. Great job Ethan!

Thanks, I hope it helps improve your prints.

I just finished my first one, now time for the second, Is there any issue with these hitting the cover on the robo?

Hi JTM88, there should be no interference with the cover of the robo. The clip holds on to the x-carriage pretty tight, so if you line up the clip to the middle of it, there won't be any trouble.

JTM88. I didn't check the Z limit. It looks like it would hit the top of the case at around 7 inches tall... so if you don't make anything that tall, you're fine. I'll be designing a remix to make up for this error soon. thanks for bringing it up, I didn't even think about the clearance for the top. Happy printing!

I love it too :) tanks for reply and keep making you greatness upgrade... Sorry for my english.... Im from Guatemala Saludos.

Im glad you like it. I've got some intense stuff in the works, so keep tuned for that.

allready made one and im building the second one, tanks a lot, really tanks. :).. i love it

Ethan, that looks really good. I like that you have it so you can just clip on or off and not have to reassemble a bunch of things. I have another design I was going to use, but I might start off with yours so I can compare. If the shrouds let enough air through, this is a very nice simple (clean) design. Can you adjust the angle of the shrouds since it is clipped or does it pretty much fit in only one angle? Having the ability to adjust it into just the right place would be slick and it looks like that might be possible to a certain degree. Thanks for sharing.

Hi danzca6, thanks for the comment. This was designed as only one angle, it directs the air at the extruder tip. But, if you glued it together at a slightly more downward angle I suppose it would still work, just be careful about clearance with the build platform. I wasn't happy with the designs that were adjustable, because they were wobbly and not stable, and they also required extra hardware. I had an instance where the duct hit the part I was printing. These ducts are very solid once you glue it together. I hope you enjoy and they work for you.
