Do you have the model of the print head itself that you could share with me? I want to use it to model up some add-ons.

Creality Ender 3 assembly

Hi, what are your slicing settings?

unfortunately not working. speed difference ten times between holes

well thanks for the impressive flow or heat graphics

I tried to find out the flow rate of the exhaust. Color shows not heating but speed of flow

so you suggest the flow should be more pointed to the center of the nozzle?
then this leads to much more faster cool down of the part based on your speed in cm / s -right?
additional it is interesting to see on the graphics that on opposite side of the ring is almost no effect of blowing ...puh

I did not think about the direction of the flow of exhaust. But I wanted to understand the effectiveness of the design in the form of a ring. On the plane in the center of the ring, you can see that there is not enough flow for the far hole. Maybe the beginning of the ring should have a larger diameter than the other side? I don `t know, but I assume

Printed and installed. Sadly the ring center is offset from the nozzle and when I did a water dimple test, the dimple was offset accordingly (about 3mm).

Any possibility of a fix or altered version?

Hi,
I know it is slightly out of center but that much? Please check my pictures - i did not have that much error.

check my pictures in the make i posted. I'll take a picture of it doing a water dimple test when my current print is finished as well.

I tried to slice your model using Cura, but I couldn't see the hole at the bottom and the air flow path.

cura does this sometimes, I have also never found the solution to this problem.
I am having very good results in slic3r though

Hi,
sliced mine with Cura in Repetier Host and had no problem at all
pls check your settings again
