The original model is large in thickness and small in height for school books in my country,
I resized it to support longer books in height "A4",
and reduced the thickness maintaining rigidity and ease of printing.
The file contains 4 pieces ( 2xA 2xB)
can be divided into separate pieces to fit only one AB set
measurements
2xAB X260.26 Y222.17 Z5.5
1xAB X143.92 Y181.7 Z5.5
