One solution is to buy a big 3D printer but 800x800 is too expensive, at least 2500 euro. So it seems 4 parts should be ok.
Connection can be made by side slides = not pushing parts together but slide one into other one. In case I would copy original, middle part will keep it together.
For now I will only weld it together and take measurements for a model.
I bought another front Brembo calipers, P40 = 4 calipers 30+34 mm, so this is the priority now. Actual calipers Brembo P2I08 uses taller brake pads than is braking surface of the brake rotors = problem and grinding pads off is not acceptable for me
