I don't believe origami plans exist on the market, but I'd suggest you contact John Gaughn at MagiCraft in Las Vegas about Origami.
I don't think you want to call Jim Steimeyer or John Gaughan about plans to build origami yourself. They will not talk to you at all on this subject.
You shouldn't be contacting either one since you don't have any idea that these are Proprietary Designs and are protected.
You need to read up on Proprietary illusions and how the industry works. http://www.zigmont.com/backstage.html
Magic Craft is David Mendoza he doesn't make origami.
