KuduStruder

Note: The first iteration of this design contained a number of design flaws that have been fixed in the current part files, so if you downloaded the originals, you may want to update them to the latest versions.

This is my take on a direct drive extruder that uses a geared Nema 17 stepper motor. It is loosely based on RoBotniK's Robotruder, but I have made a number of alterations and improvements. Features include:

1) MK7 equivalent drive gear w/ 8mm ID (no need to turn down shaft on a lathe)
2) Compatible with both 1.75mm and 3mm filament
3) Compatible with Gregg's/Wade's mount bolt pattern
4) J-Head compatible
5) Quick release mechanism for lightning fast access to your hot end
6) Retainer clip for 2mm ID x 3mm OD PTFE liners so you can print with 1.75mm PLA or ABS filament using your 3mm hot end
7) Integrated 40mm fan duct to cool J-Head and/or Metal Magma hot ends
