Foot for vintage Singer 401 series sewing machines

The feet on my vintage Singer 401g were degraded to the point that the head of the screws were beginning to scrape the worktop. I printed this foot using TPU and it works very well. I have printed from PLA, but your work surface needs to be very flat to avoid the machine rocking a little. I used the generic TPU profile and it worked quite well. There was a little stringing between models when I printed 4 at a time, but this will depend on how dry your TPU is
