Print with no supports, use the SVG as a negative part to cut a notch in the face of the acorn. Or don't. I'm not in charge of you.
The author remixed this model.
I removed the top few layers to make the face of the acorn flat. Then I created an SVG in the shape of the bottom to cut a notch to provide similar shaping and differentiation between the “cap” of the acorn and the body. This way it can be printed without any supports!
