These can be used as a temporary fix to replace your backing plates on a Craftsman LT1000 Lawnmower. These are essentially 1 - 3 times use (at least with PETG), and will need to be replaced after an extended period of time, as the backing plates will see some heat as well as impact forces. It is possible that if you were to print this out of an alternative material (e.g., Nylon, ASA, ABS) that they could last longer.

There are three different sizes of the backing plates, as they seem to vary based on the depth of where they sit on the mower. There is a 2.5mm height version, a 2.75mm height version, and a 3mm height version.

When you go to actually print this, in your slicer you want to have many different walls as they will need to be able to absorb some impact.

I am not responsible for your use of this with your Lawnmower.
