"Cup Hat" Lid

Our cat kept hopping up on the coffee table to sniff or slurp from our cups. So, I made a lid to set on the cup without fully sealing it. My wife kept calling it a Cup Hat. I named this version that for reference. Our drink cups (as sen in the photo) vary between 90mm-92mm diameter openings, and this lid self-centers to fit both. The inner protrusion is designed to center the lid in the cup opening, and is tapered in such a way as to require lifting the lid straight up approximately 1 cm in order to access the cup contents. The animals that push or lift from one side will have to try extensively to shove it off. Our cat has now given up on accessing the cups; works great. I'll print a couple more in clear or white when I get those spools in the future. If you opt to print with 100% infill it might feel more substantial, but it works by physics and design regardless of weight.

If anyone knows whether there is a dishwasher safe way to 3D print, my wife would like to know... lol.
