Cat-proof glass cap

If I have a glass of water on the table, my ninja cats take advantage when I blink to jump over the table, drink and wet their paws in my water, so I made this cap to protect it.

If you want it really cat-proof, try to adjust to the diameter of your glass (with 2mm more). The model has a 90 mm inner diameter, so scale it in slicer as needed.

I also works as coaster.
