When I started designing the rover, I ran into a significant obstacle trying to find inexpensive tracks / treads. I had some success 3D printing ones with flexible filament but the total cost was too high.
That's when I stumbled into these... 'chain bracelets' from Oriental Trading. You can buy a dozen for less than ten dollars; which will make six rovers.
