Bolekai the witch

i need a witch for the party next session (pathfinder 2ed) so i search on the web what i can find, i take the head of a (really beauty and almost naked) witch and put it on the body of the chaos sorceress, not that i don't like the witch body but i need to be more dressed.So i do some blender kitbashing + some sculpting and remesh it to a printable witch.I painted her in 4 color i just need to know how i can put the 3mf file... :Dsorry i'm new to makerworld.
