Plant pot with steps

a friend saw this design and asked if I could make one.

The one she saw was decorated with little people and tiny cactus

It's 20cm diameter and the steps go close to the centre.

I printed with a raft, to make sure I didn't pick any filament from other prints on the white base, but it should print without if you have a clean enough plate.
