Printable pin-pointer tool to slip onto end of bit in router

I seem to have a vague memory (and lately almost all memories are vague memories) of someone having made a printable pin-pointer tool thingie to slip onto the end of bit in the router, so as to confirm origin and alignment, more precisely, without having to swap a regular end mill out for a v-bit. Am I imagining that, or did someone really do it? It would not be hard to model, but I figure if someone’s already modeled and tested it…

FWIW, here’s what I modeled up, and currently printing. Will see how it does.

That could be good! A couple of features I’d love to see, I’d like to see it made with conductive filament so that it could be used with a z touch probe and to go along with that, made so that the tip of the pointer is always the same distance from the end of the router bit. Those two features together would make it very easy to quickly zero out the x, y and z axis.

@Rocco85 those features sound super cool. Those things are beyond the scope of my current effort.

I have a material base (large piece of particle board) with a printed full color sheet of paper stuck to it with adhesive, and the paper edge is not perfectly aligned with the material edge, so aligning the material against my perfectly placed dowel rods on my table edge, is not enough. I need to offset the material such that the printed paper is set to proper alignment with the LR4. I have crop marks printed in the corners of the paper, and this tool should hopefully help me “hit” those marks.

The 1/8" inch one fits splendidly.
