It would be nice if you attached a drawing or photo of your details. From the verbal description it is difficult to understand what exactly your problem is.
As for meters of this type, I have worked a lot with similar ones, only with a smaller stroke of the measuring tip. I can't say anything bad about him. The only limitation is the angle of inclination of the surfaces, which are almost vertical. The measuring tip sometimes cannot pass over such surfaces - this is still not a CMM.
