Lawnmower Blade Insulator

thingiverse

I created this because the plastic washer on my electric lawnmower had given out from years of wear and tear. They're designed to fail first, sparing more delicate parts from damage caused by rocks and tree stumps. Instead of buying a new one, I thought, why not 3D print it? This is still a work in progress - the first version fits better, having been made directly from measurements taken from the broken part. The second version has the actual shape, but needed extensive grinding with a Dremel to fit properly. Time will tell how long it lasts. I'd like to thank John from the MP Select Mini Facebook group for his help in designing this piece.
