This is a replacement rubber foot for an Underwood Rhythm Touch typewriter from the 1940s.
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 of my Underwood Rhythm Touch. The feet have a metal cup on top, and a wide-profile rubber part underneath it. A screw holds everything together. There are some features of the original foot that I reproduced in details, like the top, but as I didn't want the use of supports I modified the bottom of the foot.
This foot is very similar to the one I designed from the Underwood "SS" typewriter. The feet may or may not have been different originally. The only difference between the two designs is the shape of the bottom of the foot: tapered vs. vertical.
