2018-03-01 v2: Added 50/50 divider for even air distribution
Simplified geometry (remove text and marks for cleaner and faster printing)
- Optimize airflow
50/50 divider inside fan connector for even air distribution
- Angle optimization for less air turbulences
Make sure the print is watertight, you don't want to risk loosing precious air from the small fan.
Use 2 perimeters and at least 4-6 top/bottom layers. The exact amount depends on your actual layer height. I highly recommend using 4 layers when printing with 0.2 mm and 6 when printing with 0.1 mm.
You may use supports on the screw holes depending on how your printer is calibrated.
