I calculated that a million ants would weigh about 5 kg. Huh.
0.2 mm layers.
Million Ants is Brown. You definitely need to use supports. Check the layers view in your slicer.
You do not need a raft or skirt. His ant base is large and should stick nicely.
The basketball is Orange. I used a black sharpie to draw the lines on the basketball.
I used a 3D pen to embed the basketball in Million Ants chest. If you don't have one, it looks fine just stuck in there.
