Toyoppe has now released one part of his Origami mecha papercrafts (Samurai Sentai Shinkenger), but it looks like you'll have to do some work to get the complete set ^^
I'm not sure if I got the translation correct, but it looks like you'll have to build the first model (Shishi Origami Mecha), send a pic of the finished papercraft, then you'll received the template for the next mecha, repeat until you get to the last one - there's five in all. Good Luck!
