DIY POWERED VENT V1.1

Powered Vent. Helps circulate air into rooms where flow is insufficient. Simply attach two 120 mm fans. I used AC Infinity MULTIFAN S7, Quiet Dual 120mm (AC Infinity MULTIFAN S7, Quiet Dual 120mm USB Fan, UL-Certified for Receiver DVR Playstation Xbox Computer Cabinet Cooling : Amazon.ca: Electronics). V1.1 Geometry Update: - Updated geometry for better airflow. - Larger vent interface for a better fit. - Increase the diameter of the fan screw holes to eliminate interreference with the fan mounting screws.
