I was amused by an attempt to monetise a similar implementation of the pixel shroom stencil, so I spent 10 minutes in F360 and made one for big books!
This guy is 17 cm wide & tall, print it at 60-70% if you want something of more reasonable dimensions :D.
STL, .step and .f3d included for your editing pleasure.
Cheers
