Underwood 11 Feet and Return Bumpers
thingiverse
Replacement feet and return lever bumpers for the Underwood 11 model typewriter. * Print 4 of UW11_foot * Print 2 of UW11_bumper No support needed since internal overhang is small and gradual enough in the small space. The overhang is due to the need to capture the screw head. 85A or higher shore hardness TPU. Use a high infill. I use 85%, which is effectively 100 for these small parts. Too low and the parts don't hold up under compression. The feet replace the rubber only. If you are missing the felt or metal cap these will not be all that useful.
