Fin Alignment Jig

This is a fin jig for aligning fins on model rockets. The stl is for a 38mm motor mount tube and nominal 1/8" (3mm) plywood fins. The Python script used to generate this stl is also here; it can be modified for different parameters. The OpenCascade library and PythonOCC bindings are needed to run the script.

Thanks to thingiverse user amiliv, who called to my attention that the script needed to be updated for use with pythonocc 0.18, and provided detailed instructions for fixing it.
