The original feet of this treadmill concentrate the weight in a very small area and easily wear holes in soft/foamy floor mats. This adapter is a snug fit around the original feet providing a greater area to spread the load thus leaving less of an impression.
Review the sketch below for dimension information. Note that the sketch is revolved 360 degrees to produce the body so what you're seeing are radii values and not diameters.

The results, I believe, speak for themselves:

When printing, it's would be good to use a compression resistant infill pattern for obvious reasons. I made mine using the following settings:
- Material: PLA (seems fine for now)
- Layer height: 0.2mm
- Top layers: 5
- Bottom layers: 3
- Wall loops: 6
- Infill type: gyroid
- Infill percent: 30%
