this is a developement of the lol doll wings liked here: https://www.thingiverse.com/thing:3225026
The original project is cool but once installed the doll, that is already pretty unstable, would not be able to stand on her own feet.
My version features two small additional wings at the bottom that allows it to work as a support making the doll very stable and able to stand.
my daughter liked it very much and is now able to stand all her dolls side by side.
i printed it with a monoprice delta with no trouble and in about 40 min
