This is a replacement foot for a bathroom scale. My particular scale is a EatSmart Precision Plus Bathroom Scale, but this design might fit other scales. I included a photo of the lug on the bathroom scale to give you an idea what this fits on to.

The bottom of the foot has a cavity to hold a little grip-pad, just like the original.

The part was designed from scratch in Fusion 360 using measurements taken from the broken foot.
