Spiked wheels Ambrogio L15/L20

thingiverse

Spiked wheels with sleeve (to protect motor bearings) for ambrogio L15/20. The wheels are slightly larger than the regular wheels, but because the spikes will dig in to the soil, the effective circumference is pretty much the same. I had to move them a little outward to fit. You can optionally print the second outer ring, and either friction fit it or use some CA glue. With these wheels, you will usually have (much) better grip on grass and less visible flattening of the lawn, but you may have to put down some rubber on the charging dock to give it enough grip there. You can print it without supports if you want. petg recommended, although PLA will also work if it doesnt get too hot. (the wheel in the picture on the left was an earlier iteration with a longer and tighter sleeve, I gave it a little more clearance to ensure it doesnt bind)
