A few simple bookmarks with a framed design. Two flower patterns with the lacy version and a plain cutout, and a bee with the lacy version. These can be printed single color, or you can print multicolor to really get the framed look. Each bookmark is 38mm x 152mm x 1mm.

In the 3MF file the sides are colored to create connecting lines in the middle layers for better stability and to prevent separate colors from breaking apart in case of lack of adhesion to each other on such a thin print. I don't recommended altering the file too much beside changing your filament colors.
