Erika 10 typewriter foot

This is a replacement rubber foot for an Erika 10 typewriter from the 1950s/1960s.

Print settings:

- I used Siraya Tech Flex TPU - 85A Filament

- Shore 95A TPU is too hard.

- Softer TPU should work as well, but I haven't tried.

- 85A gives decent grip on a smooth surface.

- I fed the TPU directly to the extruder, no PTFE tubing.

This design is based on the original feet. I tried to reproduce them as closely as possible.
