This is the first thing that i have modeled myself. I made this model as a gift and was really suprised how good it turned out, so in case you want to use it too, feel free to do so.
I have hardly any experience with 3D printing, as i only bought my printer a week before modeling this, but I used these settings:
I printed it on my Prusa MK3S+
.15mm
15% infill
PLA
use supports for the leaves
If you print the leaves in the orientation in which they will later be attached to the tree, you avoid having a “bad” and a “good” side (this happened to me :D)
The author marked this model as their own original creation.
