My wife have see somewhere such a thing and was not happy with dimensions so I created one in SCAD to fit her needs.

It stacks up using the pins, you need to print 3xPot and 2xPin for one 360 ° circle having then 6 separate branches to put small flowers in.

Enjoy!

By the way, updated also the scad-file, and added version 2 to make the wall a bit thinner :)

And I added a set of garden tools to put into the hole of the top :)

p.s.: You see My wife wanted some more for daughter and daughter in law as well :)
