This is a remix of my Ryan King Pumpkin.

I recommend using supports with the pumpkin tilted back a few degrees. Not so far that you need supports on the stem, about 30 degrees will do. Also, consider adding a 5 mm brim to support the second layer, which may have unsupported loops depending on orientation.

I made yet another jack-o'-lantern from my original pumpkin.
