This is an update for Altrome's bowden extruder for the BCN3D+
His bowden method works great, but the BCN3D+ has changed after November 2014, so for all printers bought more recently, with serial numbers starting with 01, Altrome's bowden support structure will not fit the extruder body.
This support fits the newer BCN3D+ machines, you can still use Altrome's couplers, though I used different ones. I'm using large 1/4" nuts, so I had to design a different coupler, included here as well.
To attach this support on the side of your printer, you will need:
2x DIN912 M5x20mm screws + washers
To attach the extruder to the support, you will need:
3x DIN912 M3x12mm screws + washers
3x DIN934 M3 nuts
For the couplers found here:
6x DIN912 M3x12mm screws + 6x DIN934 M3 nuts
For the bowden system, you need PTFE (Teflon) tube of 60 to 70 cm and two straight adapters.
