Readymechs like the one in this picture are free, flatpack toys for you to print and build. They are designed to fit on an 8.5'x11' page and printed with any printer.
This is the list of all you’ll need:
- double-sided tape (or regular one-sided tape, folded)
- thick matte paper
- 10-15 minutes for build time.
Of course, you can try printing empty models and colouring them afterwards; or start a fresh 3D model with some discarded cardboard elements, such as tissue rolls, boxes... Now this is something easy, creative and funny you can do at home with your children (or by yourself) on a winter evening or a bad weather weekend.
