This is a replacement rubber foot for a Remington Vertical Adder Model-21 typewriter. It should work for other large Remington machines, in particular for the Model-23 Bookkeeping Machine. These feet need to be mounted into the existing foot hardware.
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.
The design is based on original Remington Model-21 feet.
Note that it might not be possible to disassemble the original foot without having to cause some damage to the original screw (which is a special part), as the end of it is riveted in place. I was able to remove and put back a couple, but I had to grind the end of the others to be able to screw them back. This is ok, but it will make the foot a little too easy to unscrew. Some Loctite might help.
My Vertical Adder Model-21 also had metal spacers on top of the feet's metal cups. One, however, was missing. I printed a simple spacer in PLA to replace it. Some stronger material, or a metal spacer, might be better. Alternatively, rubber or TPU spacers should work.
