Summary Dude, you spelled "incremental" wrong. . No, actually I didn't. A few woodworkers have used the Incra Set-up gauge as a part rather than a tool to add precise indexing into homemade jigs. . Well, with a 3d printer, we can skip the silliness and just make our own indexing rack to whatever specifications we want. . Here's an old Stumpy Nubs video where he uses one for a high-precision router fence. https://www.youtube.com/watch?v=vtGht9YmG8o
