thingiverse
The new extruder, based on the original design, includes additional support structures for hassle-free 3D printing. It is a 5.1 version specifically designed for 1.75mm filament. The small and large gears have been modified to work with a shorter screw tractor. A chamfer has been added to the small gear to eliminate the need for screws, while the large gear has been shortened to fit the screw tractor better. Both gears feature smoother teeth. Despite using a worn-out gear for demonstration purposes, the extruder can be used with the included gears. The source code is provided, and this design is compatible with Graber i3 printers. Additionally, it uses a carriage adapter for long motors found on Thingiverse and reprappr.blogspot.com.br.
