Will it fit he version 1 fan bracket?

If your referring to the Wanhao i3 printer being a version 1. I believe it's the same as the version 2. you can always sink the part in the slicer and just print the upper area of the bracket and test it. The design has a 40mm distance between mount screw center lines if that helps.

Okay, Im kind of lost. Ive got a i3 v2.1. What files should I print?


1 - fan shroud body ver8. The one with pads is there in case you have a curling problem when printing.
1 - Fan Cover Ver 2 or the other one if you want to use a screw and nut to hold it to the fan on the one end.
4 - Fan shroud nozzles (You glue them in to the fan shroud body. I use Nozzle_01

This should work for the Wanhao i3 v2.1

Nice! Thanks for the fast response

For those who like this design and have the newer Wanhao i3 Plus. Doomkill and I will hopefully have a working model for you in the next week.

Looking forward to it!

great design / great work - I use it on my Wanhao I3 PLUS and had to redesign the mounting - because the high of the fan-mount is different between I3 and I3 PLUS. To fit perfect the cooler should be 6mm longer - with this version the nozzle is not centric.
do you have the possibility to stretch the airflow canal from the mounting plate to the ring about 6mm?

thx a lot!!!!!!!

Send me a message with your email and I'll send the stl file off to you. I've got the 6mm shift you wanted done but I'd like to adjust the height also. What did you have to do to the mount area to make it work? Maybe I could get your stl and update the cad model then. You can try it out and we can make adjustments from there. Once we have it right we can post it up for other users then.

Diver, Sorry for the way overdue response.

I've never run the Dii cooler before so I can't give you a comparison. I've been running this one since I created it a year ago, and i have never gone over 50% fan speed for a print I've done yet. But I have not printed much with really tiny detail like action figures though. Maybe another user can answer that question a little better.

How does it compare in performance to the Dii cooler?

I've mostly found it useful when doing the brim or a small part that I can look in and see the part. Nice to check and watch the nozzle.

Now it is definitely not the same as a non shroud design. First of all it's still dark by the nozzle so you need to use a light to look in. And it is a limited area you can see of the entire part. But I've thought it worth it.

Cooling wise I've had to lower my fan speed down to 50% or less, otherwise I start cooling off the extruder itself. So air flow is good. I have not gone through any special print test to compare or anything like that.

Great looking cooler! Love the viewing slots. I'll have to give it a try.

Not a bad idea at all. It would be nice to actually see what is printing! Every time I print and test the newest and best design.... someone comes out with something better. Any chance someone has printed this and compared to one of the other blower shrouds?
