This remix of the Demon Hands Bookmark makes the models larger and stronger.  The Claws are 25% larger, and the Bookmark is thicker (1.75mm) and longer (100mm).  This makes the bookmark more rigid without affecting the book or the binding, and long enough to still fit inside a typical paperback.  Also, the slot to attach the Bookmark to the Claws has been rotated by about 2 degrees to give more side support for the increased size of the Claws.

Printing:

Print both parts, then press the Bookmark into the slot on the bottom of the Claws.  A small amount of glue may be needed to keep the pieces together.  Ensure the glue is dry before using the bookmark – you don't want to damage your book.
