Reading through this, it really strikes me that you're using the wrong printer for the job. This sort of component is a natural fit for a resin printer. The registration slits from #8 can be created reliably with a resin printer, and I'm confident you'll get better dots as well. Furthermore, the speed of printing is by Z axis for a resin printer, not volume of the part. So you can print as many wheels as the bed will fit in the same time as one, which should only be about ten minutes on a resin printer. Resin also has a lot more flexibility in its properties than fiber printing can, the toughest printing resins are tougher than any fiber for this application, so the parts would last longer. Once you have the process dialed in, you can probably print these in layers, which can be clipped apart and UV treated in batches, or maybe just use a magnetic fixture if you don't mind attending the machine more closely, they'll just pop off of one of those. It reads like #8 sent you off on a substantial mission because of printer fidelity in the registration spokes, a resin printer would let you explore that design more thoroughly.
