Spritzstruder

I wanted a paste extruder for my Mendel90, but RichRap's version took away some of my x-travel. So I tried to design a new model based on some things i found on thingiverse.
The mounting holes are standard 50mm.
Happy printing!

Note:
I had some Issues with the gearratio as my stepper was to weak to operate the extruder. So use a very strong Motor or one with a gearreduction.

Another Note:
By now this is only a proof of concept, since I didn't (and most likely won't in the near future) find the time to update this extruder so it actually works. Print at your own risk and feel free to remix ad edit so I don't have to ;-).
