So I don’t actually have a 3D printer, but from my humble perspective, why don’t you just flip the print and print it on a separate orientation. So the top heavy part is now on the bottom or add extra struts for support to increase the mass of the unstable portion if you are not able to rotate the orientation of the print
If you’re open for more unorthodox rambling, is it possible that you can pause the printhead once you’ve printed the initial base area and then tape that down to the table or apply hot glue or another temporary adhesive to provide rigidity?
