Modified RepRapPro Huxley Extruder

thingiverse

This modified RepRapPro Huxley extruder features several improvements for smoother operation and easier maintenance. Key changes include: 1. Herringbone Gear Set: The gear set is printed at high quality, with teeth carefully cleaned up for accurate mesh. A jig helps in setting the stepper motor shaft distance from the hobbed bolt, ensuring proper alignment. 2. M6 Block and Idler Lever/Handle: Printed parts are fitted together, with adjustments made to increase clearance and lever opening. Ends of the idler are rounded, and bridge section is filed away for added strength. 3. Spring Compression Rods: Longer M3 threaded rods replace set screws, secured by wing nuts for easier adjustments without tools. Holes in the idler are elongated to allow for greater lever opening. 4. Thicker Tongue: The tongue that holds the Bowden tube end is made thicker, reducing movement and ensuring a snug fit. This improvement increases stability during retracts. Overall, these modifications enhance the extruder's performance by improving gear mesh accuracy, increasing clearance and leverage, simplifying adjustments, and securing the Bowden tube end for better stability.
