80mm T-section Valve for airflow control

thingiverse

I Wanted To Create Effective Ventilation For My 3D Printer. So I Connected It Directly To The Main Ventilator In Our House. But Soon Found That Lack Of Control Over Airflow Became A Major Issue, Prompting Me To Find A Solution. I Designed These Parts Specifically To Fit Within A Standard 80mm Diameter T-Section, Allowing Me To Easily Increase Or Decrease The Flow Of Air As Needed. To Attach The Lever, I Utilized A M3 Bolt, And Fortunately, The Hole Was Already Incorporated Into The Model.
