Readymechs are free flat pack toys that you can easily print (and very carefully) build. All the toys are designed to fit on a regular 8.5 x 11 inch piece of paper and printed with any printer– obviously the nicer the printer (and paper), the better the toy. Every toy can be assembled with double sided tape, matte paper, and 10-15 minutes of extreme origami like patience. This tentaclopse by Fwis is one of my favorites, but the entire new 002 series are adorable.
