This is a basic flower pot that I designed up in Solidworks. It has a drain tray to it as well. I used blender to add some floral texture to it. Overall they look pretty good. They can be printed out of whatever you want, I just used PLA. I only added supports to the overhangs in the tray, otherwise left the outer design to be printed with no supports at mostly default settings.

The base design is about 100mm Diameter x 100mm tall (4" x 4"), but it can be scaled to whatever size is to your liking. I have uploaded all the stl files of each planter along with a 3mf file that contains each pot on a separate printing plate so can easily print the one you want. Thanks for checking it out!
