We've had an event in a local library, where children could come in and decorate this little tree to their liking. You can do the same at home, pickup whatever crafting tools you have and let your imagination go wild. Sky is the limit.
I have this as 3mf project from PrusaSlicer. I used it only for creating the hanging circle and slots. Keep these (or delete the circle if you don't like it). Use your settings for printing (just click don't transfer it).
The author marked this model as their own original creation.
