I saw Mikael's model a few weeks ago and thought that it could use some tweaks. This set me to work redesigning the model from the ground up in fusion to incorporate a trickle flow system that allowed water poured in the top to make its way down the levels of the planter. I also took this opportunity to change the scale of many of the individual chambers in the model to allow me more options for which plants I was going to use.
TLDR List of Major Changes:
-Changed the shape and size of individual chambers
-Model model generally larger
-Added slopes to chambers
-Added drainage holes to chambers
-Restructured walls to allow for the waterfall effect
-Deepend bottom area to allow for grass/moss and other water-loving plants
-Made the model much heavier ie. it uses much more filament now
The author remixed this model.
