Книжный счетчик - электронная бумага и Arduino............

No support required.
No AMS/MMU needed — each part prints separately, making this project accessible to everyone.

Backstory:

My wife reads over a hundred books a year and tracks everything on Babelio. A month ago, while scrolling on social media, she showed me a book counter, the kind where you hang little number tags. She liked the idea of having something visual in the living room.

I wasn't in the mood to recreate someone else's design, and I wanted something that matched her mix of paper books & eReader reading. That's how this project was born:
a mini eReader embedded in a decorative bookshelf made of fake books.

Note: The display text is in French. The display shows «Livre lu» (0 or 1 book read) or «Livres lus» (multiple books read). If you prefer another language, the text is easy to modify directly in the code.

How it Works:

A base that holds two supports, where the e-paper module is placed.

Six fake books, with textured, printed covers bent around 3D-printed «pages» (see assembly video below).

All books clip onto the base for a clean visual finish.

A battery-powered 2.13" e-paper display shows how many books you've read this year.

The display comes with built-in buttons. No soldering needed.

Controls:

Short press: +1 book

2sec press: -1 book

Reset: Turn off the display → hold the main button → turn it back on.

Future improvement idea :

I don't have the knowledge (yet), but the dream version would scrape your Babelio account automatically once a day (Wi-Fi on for just a few minutes to save battery).
If you implement this, please share your code — I'd love to update the project.
