I live in a very common house in the netherlands from the late 80's .
In my front door is an letter-box opening what is missing a hatch, because of that there is a draft coming from it, especially in wintertime.

You can find “brushes” for it but they don't fit nicely when (double sided) taped on.

Found a brush from a (Dutch) hardware store (dát zeg ik!!!) . Screw the brush/frame into the printed spacer and tape it on the door (its a “plastic” door and i don't want do drill into it). it fit around the piece of the letterbox at the door and make it isolate better.
Because of the dimension i have to print it diagonally on my Creality k1 -max :🤷.
