I was thinking late last night about those trimmers! This final design has changed quite a bit from my original concept, and so it would seem that they will not be accessible with the can installed. One possible solution came to mind this morning—I could very slightly enlarge this PCB, so that it will not fit inside the can. I would use it as a base for the can, with cutouts for the brass clip which secures the can from underneath to fit through. For service, the can would be removed. Once adjusted, it would be reinstated. I will draft up an idea today for better clarity.

I have used OSH Park (https://oshpark.com/) in the past for PCB production. In fact, I used them to produce a PCB for the replacement multi section capacitor (see photo).
