Reworked Parts for Secret Lock Book

*Update:* I fixed the rotation and cutting of a few parts.

A few modified parts for the Secret Lock book (https://www.thingiverse.com/thing:2605787) that make it easier to print and cleaner to paint. Just paint everything first before gluing it together.

There are a few more simplifications to be had (for instance with the "paper" and the spine base) but this is very printable now.

Unlike the original that clips together you will need a M4 screw, some matching nuts and maybe a washer
