Doktor Bibber / Operation

I lost a few parts from that game.
So I asked google to find pictures of this game.
I took also photos from the remaining parts by my own.

With these photos and paint.net...
For each figure:
I took the outline of one figure in the picture (not really exact but doesn't matter) with color correction and magic wand.
Coloring the selection full in black.
Copying these black selection into inkskape.
Path->Bitmap.... (convert pixel graphics into vector graphics),
deleting the pixel graphics,
resiceing the vector graphics to the right size and
Path modification->B'ezier... (to get a readable file for OpenScad).
Safeing to a .dxf file.
Finish.
