Extrusion cooling fan-holder/cowling for MakerFarm Prusa i3 - Version 3
Description
Update 12/7/2014 ---- Uploaded Two New Versions Of The .Stl File: 1. Should Be The Same As The Original, But Only Contains A Single Object (Some Slicers Have Issues With Multiple Objects In A Singe .Stl File). 2. Without "Manual" Support Structure; It Must Be Sliced/Printed With Support Turned On. I Wasn'T Real Happy With The Support That Slic3R Generated For It; Particularly Under The Large Horizontal Overhang; I Think It Should Have Printed Support Under The Entire Surface, But It Only Supported The Edge, And Gap-Filled To Make The Surface... ---- After Using My "Version 2" Fan Holder (Http://Www.Thingiverse.Com/Thing:216229) For A While, I Had Two Problems With It. First, It Totally Obstructed The View Of The Print Head, Making It Difficult To Monitor The First Layer Of A Print. Second, The Nozzle Was A Bit Too Small; It Was So Close To The Extruder, That It Deformed Slightly From The Heat. I Had Actually Gone Back To Using My First Cowling (Http://Www.Thingiverse.Com/Thing:213416) With The Second Version'S Mounting Parts. ---- This 60Mm X 60Mm X 10Mm Fan Holder/Cowling Is Designed To Replace The Left Side-Piece Of The X Carriage (See Pictures). This Fan Holder And Cowling Has That Part Integrated Into The Design. It Has No Adjustments For Position (That Should Really Be A Fixed Location, Dictated By The Carriage And Extruder), And Holds The Fan More Rigidly Than My Previous Designs.
