There are many versions. The black PCB is mandatory. Try to get the version with the off-centered hole rather than the center one.

AliExpress FULL, NO D-CUT
Powge can sell shafts with the D-cut already, but it's bertween 10€ and 20€ for 1 shaft; which is quite expensive. You can order a round 5mm shaft elsewhere (for like 2€) and do the D cuts yourself, this is a much cheaper option
