Every month we develop a new World one can 3D print. Thus far we have designed many interesting Worlds kids love playing with such as Farm, Shop, Trucks, Continent Puzzles, Building Blocks, Marble Tracks, Car Tracks, Solar System and more. All you need to do is 3D print these at home or at school on our recommended 3D printer. Your monthly subscription purchase gets you access to the whole library of our Worlds. You can print as much as you want or need whilst you are subscribed to Why Toyz. The moment your subscription ends you will no longer have access to our Why Toyz content.
