This is a 3x1x10u Gridfinity compatible model to conveniently hold a book (up to 28.75mm wide) without taking up much space. A double-wide 3x2x10u option (for books up to 57.5mm) is also available in the profiles.

For stability when inserting and removing your book, I highly recommend the Clickbase Gridfinity baseplates which allow the unit to snap into place for additional stability.

This model was made using this parametric Gridfinity system, thank you to the creator for this excellent project!
