One of the rubber bungs has come out of place on one of my build plates. Not completely out while printing thankfully, but loose enough to worry me.
I’ve prised it out completely and cleaned everything as much as possible, but when pushing it back into place the air pressure pushes it back out again. I’m obviously not getting all the surfaces squeaky clean, I’m not sure how I’d clean them any more.
Any advise how to keep this in place? I can and don’t mind drilling a tiny air hole on the top of the plate, don’t really want to, but I could.
