This year, we were having trouble getting hubs to fit our pneumatic tires. Our solution was to modify the AndyMark hub to fit our tires as a center piece then use 2 milled aluminum plates as beadlock rings to sandwich the tire and inner tube together. We printed several full sets as backups but at the competition we attended didn't need to change a single one. Even now, after doing numerous demonstrations they've held up very well. In addition to our wheels, we also printed some pieces to join tubing on our superstructure. These proved to be fairly strong but were reinforced with some gussets.
