Really cool! One thing I sometimes concern my self about is the minimal (comparatively) pollution my bicycle tires make. I would LOVE to print out this design on bio-degradable filament. It very likely wouldn't last as long, but that's fine if I'm even further reducing my impact. *Also I almost exclusively ride in urban environments.
Note: most biodegradable filaments are only degradable in industrial-level compost facilities; however, they do break down a lot quicker than conventional plastics in normal conditions.
**Can anyone find the .stl? :O
Biodegradable filaments are usually also rigid. So instead you could just take off your tire and ride on the rim to get similar results.
