yeah its the "wertstoffhof" of my city and they usually dont give away stuff either but i asked nicely if i could look for a spare part for one of my keys!

"One special thing about these keyboards is that they changed the switch type every year; they can be found with "real" white Alps, "real" Cherry MX blues, fake Cherry MX blues, and SMK Monterey switches."
