Printed in on an Ender 3 S1 Pro. PLA with 200 degree nozzle and 60 degree bed temps. This print shouldn't be picky about material, fill, etc. Slice with the settings you feel appropriate for the weight of the book you plan to display.

The picture is done with zero top and bottom layers for the mesh effect. The pieces will slip together and stand but I recommend gluing them for better stability.
