The controllers for vintage Singer sewing machines have four rubber feet which get squashed and damaged over time. I copied the original design and printed four of them out of TPU. The orientation of the model requires support but this yields the best results. I printed the feet one at a time to reduce the chance of stringing between objects, but you may have your profile for TPU more tuned in. The removal of support may take some effort, but I found that it eventually came out quite cleanly.
