Geometric Hex Embossed Planter

I have a few different versions of this, but this one is my favorite. 

There is a 190mm version and a 95mm version. For those two sizes m3 screws can be used in the holes in the bottom, and then the base hangs on but can be removed with a 45 degree turn.

For any other size you will have to scale the planter and the base, but the screws will probably not work. Most people probably won't care about that.
