This is a printed alternative for the pretty pricey center nut tools for the Bafang BBS01/BBS02 (A and B) motors. This tool works just as good and did a great job for me.
You need 4 M3 hex nuts and 4 at least 35mm long M3 screws. Depending on the build date of your motor, the nut might be further inside. I came across this problem during the disassembly of my second motor, so I had to switch to 45mm screws.
On top is a 30mm hex, which I did use with my large adjustable wrench, any other tool should work as well, maybe your hand strength is enough already.
