The model from the Processing sketch wasn't manifold and i currently saw no way to improve it. Thus i rewrote the sketch in order to produce DXF files and extruded them with OpenSCAD. Details and Processing Sketch:

The print should works now. Will test it next week. I printed the thing with MakerWare with white PLA on Makerbot Replicator. MakerBot's Slicer results were defect. Skeinforge worked quite well. There are still errors in the print which i think are maybe Replicator's plunger's fault.
