British Matt Denton used a 3D printer to build a larger copy of a Lego kart and rode it.
The device was created from a 3D-printed construction set and is equipped with electric motors. Previously, blogger Matt Denton had already built a smaller kart for his son, but he grew up and no longer fit into the seat. He had to build a larger car - only this one is now being ridden by a happy father.
