40x20 Blower Mount Printrbot Fan Shroud
Description
With This Shroud, You Can Mount A 40Mm X 20Mm Blower Fan. This Is A Huge Improvement Over The Stock Fan. It Can Be Used In Conjunction With Another Fan Shroud Underneath. The Blower Tilts Sideways To Accommodate The 90 Degree Extruder Configuration Required When Using The New And Improved Printrbot Plastic Extruder. This Prints Fast And Uses Little Material. It Should Print Without Supports. The Shroud I Used Is Here Http://Www.Thingiverse.Com/Thing:740810 As Well As A Spacer For Smaller Shrouds. You Can Add A Second Blower With This Thing Http://Www.Thingiverse.Com/Thing:911720 It Uses The Same Size Blower. Tips: Install The Bracket And Fan Shroud Before Mounting The Blower, Which Hides A Screw. To Install, Put The Fasteners Through The Mount First Because You Have To Tilt Them Slightly. The Allen Wrench Just Clears The Duct. Mounting The Extruder 90 Degrees Also Hides A Screw, But You Can Access With A Ball-End Hex Key. Edits: Version 3 Tilts Bracket Up A Couple Degrees. Also Shortened Bracket Height. Version 4 Is Now Solid And Manifold. There Are No Internal Cavities. V6 Increased Clearance For Nut. Improved Air Duct. V9 Cleaned Up
