2 and 3 stitch zigzag cam for Bernina 217

[sandmanred]

Here is a design for a cam for a Bernina that does a 3 stitch zigzag and a 2 stitch zigzag.  I've printed and tested the 3 stitch version and it works great.  The images show it took me several tries to get the design right, the cam installed on the machine and the last one shows the face of the cam that should face the operator when installed on the machine.  I'm not sure of the polymer it's printed of.  The two stitch version has not been tested yet.

I got the 2 stitch cam printed today.  It works just fine
