Parametric hinged book cover

Want to make your own book? Here's a parametric template for those magnet-shut books that are found everywhere these days. It's based on A5, but is fully parametric (the thumbnails show two books with completely different parameters).

The SCAD file and paper size conversion tool: https://github.com/l0b0/metal-book/

Possible mods: Different closing mechanism, different materials, etching or otherwise decorating surfaces. I'd love to see more fancy books at Thingiverse!
