Snapmaker U1 fan duct

The built-in drivers reach temperatures of up to 90 deg. Celsius which may reduce the lifetime of the drivers.

A fan duct with a 40 mm Noctua fan (type NF-A4x10 40x10mm 5V PWM with USB connector) reduces the temperature from 90 degrees Celsius to approx. 50 degrees Celsius by blowing outside air through the side holes. I designed a fan duct which can be sticked onto the right side of the printer - no screws, no disassembling, just use double-sided tape to fix the fan. See pictures for more details.

I used the USB-connector at the rear side of the printer to plug in the fan, i.e. the fan starts with the printer.

Print it with either PLA or PETG with a 0.4 mm nozzle and 20 % infill. It should work without support

Edit: I added a version for a 60 mm fan.
