I was looking at the various shape generators available in Tinkercad, and came across a random tree generator...

It might be possible to print this on the anycubic photon with almost no supports. It might even be possible to first import this into Meshmixer to apply a textured effect on the trunk/branches with one of the brushes.
It's not much, but hey, it's a free tree generator
Note that I have no plans to try it out, I just remembered this thread when I came across the shape generator. Enjoy!
