Usually you try to avoid overhangs but this experiments makes you realize of the true limits of the 3d printer.
I'm gonna try the Pin Support Challenge next weekend.
Tagging/highlighting cross my mind but I did want to keep this project as simple as possible. Tagging could be possible if I include a sqlite database but I don't think highlighting is possible in the Kindle web browser.
Outside of this project you can get tagging with TagSpaces[1] desktop app and highlighting with the SingleFile[2] web-extension.

If the e-reader have a web browser it would work without problems, maybe adjusting css properties a bit.
I save articles into HTML files with TagSpaces or SingleFile to read them later but I could not find a way to serve them easily to a Kindle Paperwhite and read them there.
I create this simple project to fulfill this need. It was just a weekend project that it's already valuable for me.
