Here’s a little ruler thing I made, with circles ranging from 0.2in to 0.545in diameter with 0.005in increments. Made it mostly to see what size cut so I can have dowels, findings, etc. would sit in the engrave or cut perfectly, because like a 1/4 in dowel actually may need a 0.255 or 0.265 inch diameter or something. You can also cut instead of etch if you are planning on pushing things through the material. Hope it’s helpful to y’all.
I included snapmarks because I used them + a jig to cut out of a piece of material with not enough slack for visual aligning. Feel free to ignore them.
