this is a remix of the mini fpv drone that you can find on this site: https: //www.cncdrones.com/stingray-y4.html.
It's from a guy who designed it from scratch, I modified it partially to be able to accommodate other FCs, it's not finished yet, there's no support for the cam (if anyone wants to do it, tag me).
To be mounted the frame needs:
4 m2x10 screws for the fc
10 m2x6 screws for the structure
4 standof m2X15/m2x20 to give shape to the frame
16 m1.5 screws for the motors
