Direct Drive 3mm-GRRF-Hotend Bowden Extruder for Huxley (with removable fan ;-) by FMMT666 Jan 7, 2013

Description

Or in short "DDGRRFHEBEFHWRF" 8D

One can never have enough 3D-printers, so I decided to build some Huxleys.
A lot of parts didn't fit or needed some improvements, so I ended up redesigning most of the machine.

Here's the result for the driver/extruder combination and a GRRF 3mm hotend ( https://shop.germanreprap.com/de/Modular-Hot-End-3mm ).

Hotend and bowden can easily be removed by only one or two screws.
The fan is detachable, which comes in handy during machine calibration or to have better sight on the first printed layers.

The design has gone through many changes, but now it works like a charm.

For the protocol:
I am in no way affiliated to GRRF and just a customer who bought some stuff from them...

I am thinking about uploading all this stuff to Github. Nevertheless I also need a 1.75mm driver, but I did not receive the hotend or filament yet. Just be patient :) Unfortunately, there seem to be not that much resources for 1.75mm filament in Germany...

Nice! I'm also using a GRRF hot-end, but with 1.75mm filament. I would like to adapt your design to this size, and also for my ORD Bot Hadron. What soft did you use to design the parts? Would you share the source files?
