imomodoll neck peg screw replacement

the current imomodoll neckpeg has been a bit of an annoyance. even with a silicone washer my doll's head keeps falling off. so i made an alternative! this one hasn't been test printed, but i made a prototype before this and everything worked well except i needed to carve a bit off near the bottom end to screw it onto the skeleton, so this should be the final, usable version without any modifications. use hot water to remove any tougher parts of the skeleton. i made this a couple of months ago, so i kinda forgot what else is needed to attach. feel free to ask questions. if you are to print this for others, you cannot monetize from it. share and print for free.
