So my puppy has picked a few of those caps from the spring doorstop that prevents the door from smashing into the wall.
Made a new one and printed 3 so far, replacing them all.
Might need a drill to make sure it fits your but on a standard spring doorstop it should fit snug. My printer isn't as precise so I had to tap them on the spring with a hammer. But all in all it works really well.
Also I included the SolidWorks file so you can make changes. Cheers.
