UPDATE 09-12-18 Change Idler to Avoid Bearing Interference on Assembly UPDATE 07-13-17 I'm Extremely Satisfied with This Extruder, Tested Only with PLA with Excellent Results. The Filament Duct Has Been Moved for Easy Filament Changes. The Idler Has Been Elongated to Guide the Filament Smoothly. Slot Motor Size Increased to 5mm. UPDATE 07-10-17 Main Body Separated from Hotend Support. E3D v6 Direct (No Bowden) Support Added Successfully. Printed and Waiting for M8 Hobbed Bolt to Conduct Tests. This is a Remix of the Original Extruder Design on Thingiverse, with Minimal Changes to Suit My Needs. One Key Change is the 9:47 Gears Ratio, Which Provides a Filament Flow Rate of 24mm^3/s with 1.75mm Filament and ATmega 16 MHz with RAMPS. This Design Utilizes: 3 - 608 Bearing for Smooth Operation 1 - M8 50mm Hobbed Bolt with Hob Centered at 23.5mm (Adjustable with Washers to Suit Individual Needs) 1 - M8 Self-Locking Nut for Secure Mounting 1 - Nema 17 Motor for Efficient Printing 2 - M4 Allen Bolts 54mm Long for Robust Construction 2 - M4 Hex Bolts for Added Stability 2 - M4 Washers to Hold Pressure Springs in Place 2 - Extruder Pressure Springs for Optimal Performance 1 - M3 Shaft to Secure the Idler, Optional M3 Bolt and Nut Available
