Smart-Flow Servo Exhaust: Active Vent System

Designed a ventilation duct with a servo motor (micro servo) controlled flap and a mount for a 5v DC 50x15mm fan.In order to mod my sunlu s1 filament dryer and improve its drying capacity.Use supports for the main part.Can be used for any other application that involves a exhaust duct controlled by a servo and a fan.It is possible to precisely control the airflow by controlling how much the servo opens the flap.For the fan I used 4 x 2.5x20mm cross head wood screwsFor the duct 2 x 2mmx5mm cross head wood screwsUsed double sided tape to secure the base to the filament dryer cover
