I printed these upside-down with tree supports for the saucer and inner pot. Brim helped the supports stay attached to build plate. I may add more designs and photos as I am really enjoying designing and printing these.
If you want to print the fuzzy planter, place both Multi-Color models on the build plate and line them up (center model works to align them corretly) then (in Cura, not sure about other slicers) use the “Per Model Settings” to select Fuzzy Skin for the outer piece. See reference image for example.
