I recently received several flower pots with plants but none of them had bases for me to be able to keep them indoors without leaking water all over. After repeated attacks from the snails eating my plants, I brought them indoors and kept them on spare container lids. I ultimately ended up designing a simple water catch tray and they have worked great since.

the 100% scale is designed to fit a 5 ¼" diameter pot with the sides flaring out to 6 ½" and 1 ½" tall. This is easily scalable up and down in bambu slicer (as I did for the two pants to either side of the middle). I printed in PETG for water retention and have not had an issue. Enjoy!
