Finally got around to printing and mounting this. It works great and my prints are definitely coming out better with the upgraded cooling. Great design, thank you!

Used v5020. Did not test yet, but the model printed very well and fit (almost) perfectly to the 5020 fan and a stock hotend. Just had to trim the hotend fan a bit at the corner that meets the model.
This looks very nice! Could you tell what software did you use for airflow simulation?
I'm trying to tweak the design so it supports a 5020 blower (with no luck so far), and want to make sure I'm not breaking the airflow.
Thanks!
@bo_2891862 Hi, i made a 5020 variant but never posted it. What i did is basically just a larger, i never double checked that for flow.
I used simscale to model the flow. Basically the tutorial of https://m.youtube.com/watch?v=Wun9EuVTV0w i flowed.
You should be able to view my simulations as they are public. This is the final one: https://www.simscale.com/workbench/?pid=3957633153304516300&mi=spec%3Ad0fd9c9e-9e4a-4f20-b226-2a175cbb3704%2Cservice%3ASIMULATION%2Cstrategy%3A28 (edited)
@K2Van thanks a lot for the links! do by any chance you still have the 5020 modified version? it would be of immense help for me.

Tried it for awhile, but it never really did a good enough job to prevent curling on sharp/thin corners for me. Caused me a lot of headaches. Eventually found a different model that has worked much better using the same size of blower fan.
@DeidreIannell_323178 can you share which design gives you better sharp corners, Maybe i can learn something.
It works great just tue 5010 fan making lot of vibrations..but it is some cheap a** fan from ali... Will have to buy some good one
The airflow is so much better and the mounting system fits perfectly. For me i also modified the original case to can fit this fan shroud (right now with my logo) i might upload it on printables with the creality logo on it
@RaresAilincai_547248 můžete prosím dát odkaz na vaše pouzdro?
@OndraBabicek_689323 Check my models for it (edited)
Nice design, i was thinking to change the Hot end with the V6 All Metal one, is this also compatible with that one? I am not sure yet if that one is longer
@RaresAilincai_547248 The V6 is not compatible with the CR6 hot end mount. So you will have to make a mount for a V6. I would advise to go for a more modern design like a Dragon (high flow). I have mounts for it up here on Printables.
I have been using the single duct on my SE, but I thought I would explore whether the dual duct gives me improved overhangs. Had to take my nozzle light assy off the fan, though. Scheming how I might get that back on, ‘cause I miss it.
Surprised to be mounting it quite that far to the right, but it seems to throw the air forward (left) a little from the two ducts.
@WhatWouldAnEngineerD Correct the outlet nozzles are mounted off center. I found that this was necessary when running the CFD simulations. In the end it is a compromise between printability (I maxed out the overhangs) and airflow direction.
As to the performance the only difference I found between the single fang which you remember the development of on the CR6 Discord I guess and the dual fang is that the single fang was better on the side of the cooler but slightly worse on the opposite side. This one is more homogeneous. Hence if you have a model with a steep overhang in 1 direction the single fang will outperform the dual. More generally the dual one will be the better compromise though.
Easy to print with no support. Got a perfect result in PETG first time.
Works well! Not optimal for use with a MicroSwiss hotend because the heatblock is larger and more assymetrical than the stock creality one. So i had to remove a few mm of the 'front trunk', so keep it further away from the heatblock. But functionally all ok !
