A set of three lightweight 3D printed bookmarks designed for durability and smooth page handling. Each model uses a different perforation pattern that gives a distinct visual style while keeping material use minimal. The bookmarks measure approximately 130 mm in length and 30 mm in width. Their thin profile allows them to sit comfortably between pages without stressing the book spine. The patterns also make them flexible and adaptable to different types of paper.

The set includes three variants:

• Bookmark Circles 001 with evenly spaced circular perforations.
• Bookmark Squares 001 with a grid of small square cut-outs and a central accent band.
• Bookmark Tri 001 with a repeating triangular lattice for maximum rigidity-to-weight performance.

Features
