plant roots planter

I made this planter and name it "plant roots planter". There are three versions:

1) one part - with drainage
2) one part - without drainage
3) two parts - to print in different colors/materials and glue together (but without drainage)

I guess the best orientation to print is as it is. Scale it to the size you need. If you downscale the version with drainage keep the thickness from the walls in mind.

Not sure whether you really need support.

I did not print it yet and made it just for fun.
