Titan Aero Fan Duct (Ender3 & Geeetech A10)

thingiverse

This model is a remix from Rascalgp's fan mount. I used the original for some time, but found that the air was not that strong on the ends. After a close look on the original, I found some walls that prevent the air flow. Also, since there is no flow management inside, the air mainly exits on the closest opening. I made some cleanings on the 3D, smoothed the interior and added walls to divide and route the air. To be sure if the strategy was working, I asked some flow tests to a friend that uses a solidworks student license. You can see the results obtained with both original and final version. Didn't change the outside shape of the part. If anyone want to change anything, I attached the STEP file. There's two versions, with and without supports.
