3D Print of MASK "CAT SKULL"

this is rough. it basically shows up as an incomplete model in slicer and is in total disrepair. I cannot figure out what specifically went wrong but for now until the maker updates something this is unprintable. Tried using several different softwares from chitubox to meshmixer and others to bring this to a printable state but the skull is absolutely damaged beyond repair and is unprintable in resin as of now.
