3D Printed RC Hex to LEGO Hub Adapter
After building BluCrawler, I wanted to see what other possibilities there were with builds using RC crawler tires. LEGO is not there yet with similar tires (closest are the Claas Xerion tires – but they are not crawler tires). Anyway, it’s challenging to mate a LEGO hub to an RC tire. There are aftermarket adapters out there, but they are expensive, so I decided to design and print my own.
