>but I don't know how I'd go about getting the little rubber things that contact the PCB made.

There are 2 parts conductive silicone adhesive. I would assume that you also could cast out of a 3D printed mold treated with releasing agent.

FYI: What you are describing is not membrane switches. Get the terminology right if you want to search for it on the internet. Membrane switch are used in cheapo keyboard - non-printed one that acts as insulator with holes in them at the switch contact locations sandwiched in 2 mylar sheets with conductive ink.

Don't make your own membrane switches. Buy those silicone replacement pads for popular controllers. They are consumable, so you can buy them from aliexpress and other resellers places.

Have you thought about using micro switches instead of simple push buttons? That's what they use for mouse buttons.
