Our kids love this books! Unfortunately the pages suffer from the extensive use. Especially the front- and the back-cover get damaged and ripped out by the binding, the cover separates from the rest of the book.
Repair Instructions
Print two of this model per page.
If you want to be fancy mirror one of them.
Insert into the binder and glue to the page. I used superglue for that and it worked well.
I minimized the area the part covers.
You can repair completely ripped books, but it is significantly easier to strengthen before the book breaks.
It probably works for other books with this binding, too.
