Almost all my typewriters have the problem of hardened, cracking rubber feet.
Does anyone here have experience with reproducing rubber parts like these?
I've spent way too much time drawing this diagram...
Like most things on a typewriter, these simple rubber feet are actually ridiculously complex and specialised parts.
This construction ensures that vibrations from the inner frame (where the typing happens) are not carried to the metal outer shell or to the surface the typewriter is sitting on.

Ah no its indicating the material:

@draemmli
It' like refactoring for coders. Not necessary but helps readability 😆
@petrisch Interesting! Why?
Because it's the part of the drawing we're interested in?
