This adapter is so you can fit the Clodbuster custom wheels by MikeKey on thingiverse.com to a 1/8 Scale HoBao Pirate MT. Tyres are impossible to get for the HoBao now and the Clodbuster uses the same size tyres but they wont fit the original HoBao wheels. My adapter means you can just fit the hub adapters to all axles and then screw the custom 3D printed wheels on. Please see the attached screenshot of thingiverse for the correct wheels. I used the stiffened ones in my build on the youtube link.
