I have to say that a router seems a bit hard core for such a small project.
I have seen these things for the Dremel, and I might even have one but never used it because the laser is so much easier for me, that should do the job fine.
It basically turns the Dremel into the router motor with a tiny bit.
I mean, one could do it with either but I think I would prefer the compact/quiet/ less aggressive set-up. It is also cheaper and more versatile.
