Door Seal

I'm not sure how to call this, but in our house we have a lot of old door who have this type of ring as a “dampener” (at least that is how I see it). Some of them are stuck/broken or really old and we needed some replacements. On the non printbed picture you can see the old example, which has been used to measure and create this. So far it fits perfectly. I printed it in PLA, bit something more flexible might be better.
