I see what your saying, but I already modified the original print to not need supports, I changed the bottoms of the overhangs to angles rather than overhangs, but cura will try and print the outer part first which is floating in mid air as shown in the gif instead of printing the inside first which would allow it be connected and not fall. And others have printed this file with no modifications and no supports, but I couldn't get any help yet on thingiverse. Thanks.
