DIY "isolation mount" / "gasket mount" for the rest of us

[tex_live_utility]

I wrote up some of my research on making the gasket-mount/isolation-mount trend more accessible to people who aren't able to participate in high-end keyboard group buys. My original post is at https://www.reddit.com/r/MechanicalKeyboards/comments/aijrnv/feeling_left_out_of_the_gasketmount_trend_no/.

Long story short, adding neoprene sheets or o-rings between the plate/PCB and the case can be a pleasant improvement to your typing experience.

Has anyone else experimented with this? Any more ideas along these lines?
