Perhaps you’re a gardener and have seen these evil little butterflies (Cabbage Moth / Cabbage Butterfly Plutella xylostella, Pieris rapae) that lay eggs on cabbage, then the caterpillars devour your vegetables. Why is it this is the only butterfly that I don’t like and does bad things? It is referred to as both a moth and butterfly so I will assume it is more annoying moth than a delicate innocent beautiful butterfly. It turns out these little delicate insects are highly territorial and wont go into a garden area where another is.
Old remedies were to spray tons of chemicals all over everything, spread egg shells in your garden, or place white paper butterfly decoys - but now we have 3D printing.
So I designed a 3D cabbage butterfly in AutoCAD end used STLOUT or 3DPRINT command to generate a STL file for use by 3D printers. I could also have easily designed the 3D Butterfly and generated an STL 3D Print export using the free 123D solid modeling software. I then printed it on my MakerBot Replicator and then affixed it with fishing line to some 1/8” copper wire.
