I have got the OK to upload the drawings and other files needed to make this Extruder to the Universities' website. Not sure if in future I may upload the files to Thingiverse, but for now you can see most of the files here:
The list of files there isn't yet complete but I am working towards that. If I find time I may add a BOM and instructions as well, but for now I am very busy writing my thesis.
Newest tests are very promising in regards to consistent Diameter. Currently its 2.9mm so the Die diameter may be increased a tiny bit. Very little diameter variations can be measured at the moment. Any current variations are due to manipulation of the not yet solid filament.
Biggest drawback at the moment is the extrusion speed, which is still rather slow, but could easily be increased with a bigger motor. At the moment the motor spins at 35RPM and is extruding ABOUT 4cm per minute.
Feel free to ask questions in the comment section, if I have time I will try to answer these as soon as possible.
Update: Added a BOM in the downloads
