I just printed this and tried an overhang test, which came out OK, but not as good as my previous Bullseye shroud. I do like how compact it is though, so will be giving it some more run time.

Just doing some test prints with this, I like it a lot. Small and narrow, there's nothing that can hit the bed clamps unlike the stock cooler or the hero me. Still need to do a bridging test.
One thing to note is that with the reverse cooling, the hotend takes longer to cool down when the print is finished.

is PETG required, or will this work if printed in PLA?

The duct comes close to the hotend. I haven't printed it in PLA, but others have and it has worked for them.

printed this in PLA and its working perfectly!

a very open and light design and super easy to get access to the hot end

Would love to see a version compatible with a 5015 part cooling fan

I've printed this for my Tronxy x5s, user for a while, change to another desing, and now i'm back to it. its so simple, and works like charm. (btw for x5s tou need to move the Y stop a bit further)

This is my favorite design out of all the ducts out there.
I need something that is very narrow all around, so that I can print multiples. Nicely done! Looks great, too!
Simple, easy to print and install. Fits with my DD.
I only know how to use Tinkercad, but I'm going to try to remix to use two stock 4010s on the sides, if you don't mind.
If it's easy for you, would you be willing to add front-loading 4010 fan ducts to the sides as narrowly as possible?
No worries at all, I'm grateful for your keen eye with this!

Glad you like it!

The part was originally made in Onshape, a browser based CAD with a free mode. Here's the link:

I also added a .step file. Tinkercad should be able to import this, with better quality than the .stl that is used for 3d printing.

Awesome! I just started with Fusion 360, so this gives me a great piece to work on. I did the two stock 4010 fans on the sides in Tinkercad and Meshmixer, but it is not pretty. I hope I can do better with your step file!

Fusion 360 is great, I've been using it a lot on new projects.

Holy heck, Fusion 360 is complicated! It's a big program, so this is taking a lot longer to learn than I expected. I'm currently working on the the long list of tutorial videos. I didn't think this would be so difficult.

to whom wants to print this;
rotate 135 degree on X axis.

thank you for the design.
