The best toy you can buy your kids is a Filabot 3D Printer. With it, your kids will be picking up plastics waste so that they can create their own toys. Don't like what they created? Never mind, put it back into the Filabot to recreate. What a great way to explore their creativity.
And no more tears or complaints that a younger sibling has broken yet another favourite plastic toy. Go print it out, kids. How?
