Robomow drive shaft

thingiverse

I'd heard my Robomow squeaking while it mowed one day and spotted that the right wheel was very wobbly. I popped off the wheel and discovered the driveshaft broken inside, prompting me to search online for a supplier. Danish suppliers insisted on selling it bundled with the motor, while British ones were uncertain if they had it in stock. Buying it from stateside would mean high shipping costs, import taxes, local taxes, so I sat down and drew up a simple CAD design. I got it printed, mounted, and running within an afternoon.
