I finished the magnetized male survivor and some assorted limbs.
I used strong neodymium magnets, and I am surprised how well they do in a project like this. The limbs have a small bit of iron wire pinned into them with a bit of green stuff to make the limb stay in a preferred position. And they stay perfectly.
I tried to use as little armored pieces in the survivors as possible, as they're supposed to represent early game survivors.
There's one left and right arm that have no equipment, one dismembered left hand, Catgut Bow and this Elder Cat Dagger that I plan to use for some other less epic daggers, like Bone Dagger.
