Miniature tools where you introduce the workpiece to the tool (like the ones you listed) seem pretty difficult in small size. Are tools where you introduce the

  The main reason I was thinking of a fixed tool is it seems that it would be possible to have more precision with it. One example that I've been wanting to do for a while is make my own slide rules. For that you need to cut 1/4 inch boards (or plexiglass) into 3/4 inch wide (or so) strips, then make a tongue and groove cut. What I came up with so far is an adjustable router table for a Dremel that you could use with a 1/16 inch engraving bit, designed for my 3D printer. Just finished making my most recent prototype, but need to rough cut the stock on a regular table saw to try it out. My initial prototype design is here: https://www.thingiverse.com/thing:5395048 https://www.thingiverse.com/thing:5395048 however I've made a number of tweaks to it (things like getting the screw thread sizing dialed in to account for tolerances on my 3d printer, etc -- eventually I'll post a fully parameterized version that can be tweaked individually). Right now it is designed to hold the Dremel in one hand, feed the work piece through the other. It has a primary pivot fence with 1/32 inch scale marks, and the second pivot fence can be attached to center a work piece (my current design eliminates this second fence and replaces it with a button that works just as good). My next Dremel related 3d design will be a mounting system that attaches where the plastic screws are that holds the motor brushes in place, then I'll see if I can do a lathe, table saw, hand held circular saw, etc).
