Hero Me Gen6 Dual 4020 - 5015 - 5020 Radial Duct for CR6 SE

Not mantained anymore

Switch to this model instead, which I made in CAD myself and it is easier to mantain and create newer versions (and you can also do it yourself because the step files are provided)

Added stronger 5020 and 4020 versions

Added V3 of the 5020 duct and V6 of the 4020 duct. They are stronger because I added a part I removed initially. This parts prevent flexing and violent vibrations (experienced them when I was testing input shaping), so the duct is now less prone to break by handling it bad.

Added new 5020, 5015 and 4020 Versions

Stronger fan mount for the axial fan and moved the duct 1 mm up for better airflow.

Added 5020 and 5015 Version

I dont have any 5015 fan to test that version. Tested the 5020 version, is tight and the cable cover wont work. But it might be useful for some of you.

UPDATED TO V4

Now I am only making one STL. I figured out how to make this easier and quicker so I can fine tune more easily (still modifying a STL)

The air is more centered in this version, for having proper cooling at the front. And the holes were fixed, reusing the stock format for making this easier to modify

The mesh is now perfect and if I have any problem during my modifications, I have a method for fixing it and deliver to you a proper file.

UPDATED TO V3

I reduced the bottom of the duct by 0.6 mm, just enough. I was having problems after reprinting the part that goes to the hotend for the 4020 axial fan. Now the tips wont touch the bed or the print and the flow is the same as the V2, that is why i am replacing it with this newer version.

I also repaired the part with the hole orientation fixed, because it had holes at the sides (bad mesh)! You should use that version, it fits perfectly.

UPDATED TO V2

Now the tips of the ducts are a bit lower and increased the clearance between the board and the duct, helping the airflow to reach the part that is being printed and avoiding problems when installing this duct

Also made the part where you hold the fan a bit thinner, but stronger to the sides.

Added the version with the hole orientation changed, now it fits right!

After A LOT of work, i managed to adapt the current gen duct for our printer!

And it works sooooo good, i really needed this and i am happy with the result

I used the HMG6-long-dual-4020-30degrees for more space, because the straight one crash with the strain gauge.

One important thing, it is probable that you would need some heat for the upper part that holds the blower. I didnt touch that part, but if i didnt heat that after printing i could not adjust the 4020 blowers in the right position, so you should check that!

Important: I am using this 4020 axial fan mounting

You also need to use the pcb housing from this link (thanks original author)

The version i am ing has a bit more space than the one i printed first, so you wont smash your cable like i did. I will reprint in PETG, but PLA is fine.

Used the same settings from the hero me fan duct: 50% infill, only touching buildplate and it worked fine.

If you can do a better job, remix it and i will print yours!
