Flower pot cat protection ring

I designed this little protection for a flower pot after it got attacked by my cat several times. She likes digging in the potting soil and afterwards it's a mess on the floor. This little protection ring prevents her from doing so. This one is designed to fit around pots with a diameter of 25cm but it should be no problem to change the size in the slicer software to make it fit to other diameters. Printing took me around 3h (0.2mm, 20% infill).

You can tell me what you think about it, or what to improve. This one my first shot and I would like to make it better.

Update:
I've uploaded another version that closes the ring a bit more.
