This was an interesting build. I could see for making dials, the ability to have 100/200 divisions for threaded feed screws that are dividable by 10 vs 360 1 degree increments. Seems there could be two rows of holes, 36 and 20. I have a 5C spindex, now I know how to make the Vernier/(Nonius that's new to me) index.
The issue I'm thinking is having room for the holes.
Also I don't think making it from plastic 3D print is the right material for rigidity, as that was evident in his video.

Thinking about it, I think there are some things you could do to help the accuracy. E.g. Press in metal liners to the reamed holes, print the shaft holes on the components undersize and turn them to fit. Still, for a 1.0 project, it was great!
For getting that busted tap out, the alum/hot water trick will dissolve a HSS tap. It's a cool trick, and AVE is a hero for sharing it. There's plenty of room for larger fasteners on the shaft, so maybe move up to m5 or m6 on the next one to make tapping suck less.
Has anyone tried this, or can verify that it works or not
Never try to tell me it can't be done

So searching for "alum hot water tap removal" in YouTube, I got 3 videos showing the process;
They all appear to be successful using Aluminum sulfate, with hot water or hot battery acid mixed with alum. Boiling water temp is shown in all three of these videos.
