I drew a picture! There is still a pretty big wobble on the core, but it was good enough to pen plot. The pen plots looked good, so next I want to rout the plates out of plywood to double check the dimensions are correct. Should also be a good next step for the setup.
I can’t get anymore prusament PLA to print the updated core for the moment. So I am going to try Technology Outlet’s professional PLA. I’ll give that a go over the weekend if it turns up on time. Hopefully then I can try the router.
In terms of bits, I was going to get some 1/4inch shank straight router bits from toolstation to start with. Then probably engraving bits from Ebay.
