LEGO Technic sets are great for creating interactive sets, but there isn’t one yet that lets you build a life-sized go-kart. So, Matt Denton decided to take things into his own hands. With the help of 3D-printers, he managed to piece together an XXL LEGO go-kart with pieces that are scaled up 8.43 times the size of their real-life counterparts.

There are long beams that make up the frame of the vehicle and the axle piece required for the steering column, but both are too long to print at one time. The axle was printed in two parts with a square channel down the center that hides a single run of square tubing, while the beams also took an extra session. The latter consists of a dovetail-shaped connector piece that holds the top joint together, and a hidden bolt for the bottom.
