E27 light bulb socket blind plug

An E27 blind plug to make empty sockets safe to touch. Knurled handle for perfect grip.It might fit E26 as well, or it could be a tiny bit too big since E26 is a tiny bit smaller. I have no way to test that though. I used PETG, 0.16mm layer height, 3 walls, 5 tops/bottoms and 12% adaptive cube infill.
