Looking to source an old mechanical Keyboard for casting project

Hey! I’m looking to make a mould of a keyboard - currently in the process of sourcing one I can use to cast? Wondered if anyone had a broken one lying around I might be able to use before it goes in the bin. Bit of a longshot - but thought I’d try, please let me know if anyone has any leads! x

I saw an STL 3d model of one for 3d printing which might be a fallback. I think it was on Printables or Thingiverse.

I will take a look and see if I have anything suitable; if I do, I will bring it over tomorrow evening.
