Book Cover

I recently got dragged to a bookbinding class by a friend. It inspired me to create a journal cover into which I can add sets of bound pages. It should be a fun project for anyone that wants another nerdy hobby in addition to 3D-printing. To add a twist, I printed it without top and bottom layers in order to expose the infill pattern for all to see. Different patterns give different looks (though some like Hilbert Curve would obviously not work). Part of the fun is playing around in Slic3r to see what you can do.

For the interior I used sketchbook paper with origami end papers to make five 100mm x 150mm (~4" x 6") signatures (this can vary depending on paper thickness and personal aesthetic preference).

A friend that actually knows what they are doing, sewed the signatures together in a Coptic stitch pattern (a tutorial in this technique may be found here: https://www.instructables.com/id/DIY-Coptic-Stitch-Bound-Notebook/) with seams every 30mm measured from the center of the fold. I used another thread running through the holes in the spine to stitch the pages to the cover (no specific pattern, just whatever functions and looks vaguely orderly).

I attached the Openscad file in addition to the STL so that anyone can make changes to the dimensions or clearances or remove the medallion hole or just point and laugh at how messy my coding is.

Enjoy, and please post any questions (though no guarantees that I can answer anything bookbinding related).

On a side note, if anyone feels so inclined to tip me for my design work, please instead donate to the ACLU, Habitat for Humanity, Planned Parenthood, or any charity endorsed by GiveWell. Thanks in advance.
