I remade my old feet a little taller (61.9mm) and able to be attached with T-Nuts. I was tired of them falling off whenever I had to move the printer, even though it was rare.

I only had m3x8 screws, and m3 T-Nuts available. I think the most commonly used is m4. But this can be adjusted/remixed by someone if they prefer.

I used Priline TPU which is quite stiff. 5% gyroid infill - Your mileage may vary.
