This could add some machinning time to your current design, but it will ensure a perfect centering of the jets every time. Once you switch to molded parts, this features comes almost for free.

Yes, very good idea. I had indeed thought about this when molding. A little harder to do with the present machining as I would need to remove extra material to create the bumps, but for a mold it's exactly what I intend to do.
I'll also get them keyed a certain way so there's no confusion as to which direction the plates go, since with the top two plates it is possible to turn them around such that the top plate blocks off the middle plate's exit.
