40mm Fan Venturi - Velocity Stack

Inlet duct for 40mm fan. Includes a 15mm clearance flat on one side.

I made this specifically for the Anet A6. It not really necessary, the a6 will run just fine without the extruder fan. But it looks kinda cool and if you want more airflow it should help a little.

Here is my goto PLA brand:
