60 X 8mm wheel
thingiverse
The original wheel of Pololu 1420, 60x8mm size, was modified to fit an O-ring for its tread. The O-ring, part no. 9452K96 from McMaster Carr with a 1.875" inner diameter, is designed to be compatible with a micro metal motor's 3mm D-shaped shaft. This modification can also be applied to the Arduino Robot; however, as I don't have access to a printer, I would appreciate feedback from those who build it and test its functionality.
