Summary

I got tired of my sprinklers breaking after being run over with the car. After I saw how much concrete donuts were online, I decided it would be much cheaper to make my own.

This is a shell/mold for a concrete donut that will fit around sprinklers. Hole is approximately 3 inches.
Text says "GET OFF MY LAWN..."
All you need is to fill it with some cement.

I printed with text facing down and supports.
