Here are some simple book dividers for pocketbooks.

26 letters + a Star… just in case :)

Letters are dispatched regularly along the side so if you only have one book for a letter they won’t overlap.

I made them as thin as possible while keeping something that would last.

I choose to print them as 4 layers of 0.2mm but you can experiment with different thicknesses.

Width: 11.9 cm (4,68“)
Height: 18.2 cm (7.16“)
Thickness: 0.8 mm (0.03“)

Filament used per divider: 20g
