An extremely versatile direct-drive extruder for a nema 17 motor.
It can be mounted as a bowden extruder (clamp included) or directly to a Wade-compatible or i3 x carriage.
Uses m3 hardware for motor mounting and clamp, and can use either a 623 or 625 bearing - both versions are uploaded.
Uses an mk7 drive gear, I got mine here: http://twelvepro.com/index.php?route=product/product&path=61&product_id=51
Allows full access to the idler teeth, even while printing - with tension adjust exposed as well.
The clamps are meant for use on a Graber i3 printer - so they use 6-32 English hardware. I prefer to use the clamp to mount the extruder, rather than the extruder with the i3 mount built in.
The bowden mounts are meant for use with the E3d hotend - their bowden tube pushfits have been drilled out, so the tube can pass all the way through - there is a hole for the tube to enter the extruder, and make sure that your filament is 100% guided.
WHY another extruder?
