Especially because the teaser image looks perfect, but the customizer was not able to deliver it, so I created a similar tree in zBrush free to use.
I used support, but it should also work without support. I also moved the bottom plate into the bottom area in Cura so it printed just 5mm of it, so that is an easy fix if you don't want a huge plate - I won't revise the thing as it printed out beautifully in the first run which took around 8.5 hrs.
Cheers
