Arduino Tank tracks

thingiverse

The shafts have diameters of 54mm and come in two different sizes: 6mm and the classic shaft used with the Arduino gear box. To create the tracks, I use EVA foam that is 2mm thick. The design consists of a single strip measuring 20mm wide, accompanied by an even narrower strip measuring 6mm at its center. Both strips are glued together at their ends, resulting in a track system that significantly reduces noise levels to almost imperceptible levels while providing excellent grip.
