Can Lid - Fits many - cat food, dog food, canned foods - TPU

Easy print, upside down with no supports. Recommend TPU or other flexible plastic. It fits tight on 4 different size cans. There are 2 different sizes in the middle area for small cat food cans, push all the way down to click on cans like Fancy Feast or halfway down for similar cans with thicker rim. Then there are 2 larger rings for larger cans. It is tight enough to hold most cans without falling off, even upside down or being held by the lid.

Print upside down with no supports necessary. I use 40% infill, 2 or 3 walls. You might want to change the number of bottom solid layers so there is no infill in them, I just use the infill for the edges.  Could also print them solid.
