I am selling my CNC (upgrading to a new one) and one interested party was an ACM (Aluminum Composite Material) fabricator making mostly boxes for building cladding. I was thinking how best for him to add boxes, basically a job-specific parametric program and realized that's what gadgets do.
Interested in seeing if anyone versed in these things might want to quote on making such a thing if the deal goes ahead. It's basically a box of X by Y size, with smaller boxes on the 4 edges and some lines that overlay some of the lines (grooving lines).
Ideally, then applying a dogbone fillet to the inside corners too, but that could still be done by hand if needed. See the attached photo pulled off the net for the basic idea. I could likely do this with a keyboard driven macro too, but a gadget would likely be even better.
