a very simple way to print art object from supports. 

It is important to enable the support generation settings in the Orca Slicer as shown in the screenshot. 

1. Enable Support
2. Style - Any
3. Threshold 70 
4. First layer density 100
5. First layer expansion - 6 (the higher the model, the more layers you need)
6. On build plate only - true

The lower circle of the first layer only serves to make the trees grow from one point. After printing, this disc will not be needed. You can change the diameter or height of the trees. 

it is made in the shape of a ball, but it can also be transferred to any geometric shape. Fusion file in download. 

printed from a glowing PLA (2h)

ideas for further models - a treehouse, an owl sitting on a branch, etc. Please like to launch a new Support Model Week competition
