Summary

So I have a Whirlpool 2in1 washer that sits on smooth concrete, and whenever the washer operates, it would "walk". So I came up with this design.
Legs :
Filament : PETG
Infill : I used 50% gyroid
Walls : 5
Top layer : 5
Bottom Layer : 4

Feet:
Filament : TPU 95a shore
Infill : 10% gyroid
Walls : 5
Top layer : 5
Bottom Layer : 4

I printed the legs on my K1 Max, took about 35 minutes each leg
I printed the feet using my Ender 3 Pro, took about 1hr 30min each

I plan on making something like this for my dryer as well, I will post those when I am done prototyping
