3Doodler has also introduced a series of STEM activity kits outside its partnership with HexaBug, though these ones don't have a pen included. One can help kids build detailed robotic dinosaurs, while the Science and Engineering kit can give life to scientific instruments and complex structures. The last one in the series is the Make Your Own Figurine kit, and kids can use it to build figures to go with their robot dinosaurs, bugs and 3D-printed miniature roller coasters.

In addition to all those, 3Doodler is also releasing new Doodlemolds to help kids make 3D-printed desserts, key rings, costume masks and eyeglasses. The Hexbug kit will come out in May for $60, along with the STEM Series sets, which will be priced between $20 and $30. Those only interested in the Doodlemolds will only have to set aside $15 for a set when they become available in the spring.
