I did a fusion 360 reverse engineering of stl files.
I modified the path of the gear to better fit and generally improved to print with FDM printer
**UPDATE 1 05/12/18***  Added a new screw to better keep in place the e3d v6 extruder with less vibrations (use a thread insert M3), added a space for collet clip, corrected the room space for the bondtech idler gear.
link to thread insert M3:  https://www.bondtech.se/en/product/thread-inserts/
**UPDATE 08/12/18*** Totally redesigned the holder for e3dv6, now is more easy to insert the extruder with collet clip and bowden tube. Change thread insert with standard nylock.
**UPDATE 22/12/18***  now 2 weeks later i can confirm that it work consistently wery well!!! No issues at all from my point of view and from the results.
UPDATE 01/01/2019 Re-upload the step files, some touch-up here and there.

So i have decided to finish building my IDEX machine at the beginning of the new year and made the choice to use a direct drive Bondtech BMG and E3D V6 combo.  My only issue was the Bondtech housing as i wanted something i could modify or mirror if need be.
This led me to design a simpler version of the housing from scratch which would allow me to make any changes i needed.  I also removed all the injection moulding features and cutouts just to keep it as simple and easy to print as possible.
The body is slightly smaller than the original it was based off of, and the filament path is a bit tighter.  The Inserted PTFE tube also goes further into the body on both sides.
There are versions for various fittings. And all are available in both left and right handed versions.
M12 press fit fittings
M8 BMG press fit fittings.
M6x1 threaded fittings
M10x1 threaded fittings
1/4" BSP threaded fittings.
1/8" BSP threaded…
