Usually you try to avoid overhangs but this experiments makes you realize of the true limits of the 3d printer. I'm gonna try the Pin Support Challenge next weekend.

PLA gets so much stronger when annealed. Would it be within the spirit of the challenge to print this upside-down so that it can support the sphere, but only after annealing? Or you could anneal the pillar with a small heater as you print it.
Oh my God I didn't even realize this was a thing. Thank you and there goes my evening! :-)
Just note that it will also shrink the print.
The bonds between layers get stronger when annealed. I don't think it will make much difference in this case since there are no layers in the pin.
If you’re actively heating the chamber to anneal the plastic why not just print in PETG or polycarbonate?
Why do you need to heat the chamber to print in PETG? Or do you mean "instead of"?

I agree, BTW, PETG is much better.
