Ống gió làm mát stepper driver Snapmaker U1 (cần quạt 60mm)

This is a remix of the 60mm version of the cooling duct from MABA. With this cooling the temperature of my stepper drivers dropped from around 85°C to 50°C. I use a Noctua NF-A6x15 5V with USB A connector. There is one downside: The chamber temperature dropps as well. That is no problem when printing PLA but could be when printing more demanding filaments. With a top cover and passive heating (print bed) you will not get high enough temperatures.
There were problems with the screw holes in the 60mm version. This remix should fix these problems.

Print:
The standard profile with 0.2mm layer hight and no supports prints just fine. To hide some layer lines on the top you may try variable layer hight.

Assambly:
The orientation of the fan is important. You get much lower temperatures of your stepper drivers if you push the air from the outside to the inside. I tested sucking the air out but the temperatures only dropped to 75°C this way.
