Silent keyboard with foam

Hi,

I have an idea to silent (a bit) the keyboard of my Reform : put foam between motherboard and keyboard PBC.

Do you think it is a good idea?

I have considered something like this but I’m worried that too much contact of the keyboard and motherboard could increase the amount the motherboard flexes in the middle. If you had a lower-density foam that might not be an issue, however.

I would be happy about any successful recipe to silence the keyboard. It isn’t that noisy, but coming from Lenovo classic keyboard (not the island style one), it is an audible difference. My colleagues in the office do not enjoy my typing.

Maybe a custom template of something like this?
