Dual hobbed bolt extruder: no-grinding attempt
Description
This Is My Attempt To Make A Better Extruder For My Big Printer. I Have A Bowden Extruder And Somethimes The Filament Has Difficult To Be Extruded. It Uses 2 Hobbed Bolt To Drive The Filament. I Have Finish To Prints All The Parts But Havent Try It Yet. Still A Wip Concept. Haven'T Upload The Body Stl File Because It Has Some Errors, That I Have Fixed Removing Some Parts With A Cutter... Update 2014-10-20 Upload Two Version Of The Main Body
