edge repelling magnets

Hello ive been planning to make a v11 mod resembling the ferrocore v2. Does anybody know what specificaly are the sizes and strenghts (in N48 for example) im the ball core so the corner and edge magnesy im the ball core and the same for the magnets in the feet of the corners and edges

So i currently main the meilong 3m. I love it but its a bit basic. So i got my hands on another meilong 3m ! And well. 24/9/25 - Took apart my meilong and rs3m 2020, and i swapped the cores ball thing, the screws and springs. Everything else is the same. Im doing this as the meilong 3m core...
