Designed to be an alternative to replacing the lawnmower wheels when you have no tread. This print fits around the existing wheel to give your mower a new tread.  This is a less expensive and easier fix to replacing all the existing wheels.

In my use case, I use it on my self-propelled mower.  My previously worn-out wheels would just spin when trying to go uphill. 

This should work on most mowers.  You may have to resize it slightly to fit your wheel when you slice it or by editing the Fusion model.  The inner diameter is 198mm, and the fit should be snug.

Use small screws to permanently fasten the retread to the existing wheel.

This will print on a Prusa MK3 if you turn off the skirt.

Let me know in the comments how this works out for you.
