well, i made it from original .nif file, but this seems that had been created the same way :)
i3 printer 0.5 mm jet
~10 hours printing, lot of work on removing slic3r generated supports and aceton vapor smoothing (20 minutes, 20 - 40 °C)
Hey, do you still have your .stl file you used for this?
the 'original' on here which you've uploaded this make to has lots of mesh problems and is unprintable, thanks in advance.
