Elegoo Neptune 3, 4 (Pro/Plus/Max) Feet

I was looking for a way to reduce vibrations on the Neptune 3 Plus and by looking at designs for other printers, I came up with this version. As I did not come up with this entirely myself, I have tagged this as a remix of another design which inspired me the most. 

Before using these feet I felt vibrations while lying on the sofa. This seems to have stopped now so I'd like to think that it has helped a bit …or maybe I'm imagining it. I'd be happy to hear about your experience after printing this. They should fit the Pro's or Max's rubber feet.

I chose to leave out one wall so it's printable without supports and it works for me. I used PLA+ with 100% infill.
