Kingroon KP3S / E3D V6 Fan Shroud with No Duct

I designed a cooling and airflow system for my friend's upgraded Kingroon KP3s to minimize setup time and simplify maintenance. After experiments, I found that a duct doesn't greatly impact print quality, enabling me to print overhangs up to 70 degrees effectively.

You will need extra parts to install 5015 fan: 

• 3X20mm hex screew
• 3X5X6mm brass insert nut
