Turn your bookshelf into a playful visual scene with these Cat in Portal Bookends, a functional and decorative STL model for 3D printing.

The design divides a stylized cat into two complementary sections: the head and front legs on one side, and the hind legs and curved tail on the other. Each section meets an oval portal-shaped panel, creating the illusion that the cat enters a portal beside your books and emerges at the opposite end.

Place the two sections on either side of a row of books to complete the effect. The books conceal the space between the cat’s front and rear, making the animal appear to stretch through your collection.

Pointed ears, small eye cutouts, a gently curved back, and an upward-curling tail give the silhouette a recognizable feline character. Flat rectangular bases complete the design, while the simple geometric forms suit modern bookshelves, reading corners, home offices, and creative workspaces.

Print both sections in the same color for a cohesive appearance, or paint the portal details in a contrasting shade to emphasize the illusion.

• Creative Portal Illusion: The cat’s front and rear sections appear on opposite sides of your books, creating the impression of an animal passing through two portals.
• Complementary Bookend Pair: The two sections work together to frame a row of books and form a complete decorative scene.
• Modern Minimalist Design: A clean cat silhouette and simple oval portal forms complement modern, Scandinavian, Japandi, and contemporary interiors.
• Expressive Cat Details: Pointed ears, eye cutouts, walking legs, and a curled tail give the design a playful appearance without excessive ornamentation.
• Oval Portal Panels: The upright oval forms provide a visual transition between each cat section and the adjacent books.
• Flat Rectangular Bases: Each section has a defined base for placement on a suitable shelf, desk, or tabletop.
• Flexible Spacing: Position the front and rear sections closer together or farther apart to accommodate different widths of book collections.
• Functional Shelf Decoration: Combines bookend use with an animal-themed display. Book support depends on the printed size, weight, shelf surface, and books used.
• Customizable Colors: Choose black, white, gray, or beige for a minimalist look, or use bright colors for a playful shelf accent.
• Scalable: Resize the model in your slicer to suit your books and display space. Scale both sections consistently to preserve their proportions.
• Optional Painted Accents: Highlight the portal panels or other details with contrasting paint to personalize the finished set.

• .STL: Cat in Portal Bookends model components, featuring the front and rear cat sections with their portal forms and bases.

• Print Orientation: Evaluate an upright orientation with each rectangular base on the build plate. Inspect the legs, tail, eye openings, and portal details in the sliced preview.
• Layer Height: 0.16–0.20 mm as a starting point for balancing surface detail and printing time.
• Perimeters / Walls: 3–4 walls as an initial setting; adjust according to the model thickness, selected scale, and desired strength.
• Infill: 20–30% as a starting point, using Gyroid or Grid. The finished weight and shelf friction also affect bookend performance.
• Supports: Evaluate in your slicer, particularly beneath the body between the legs, around the curved tail, and wherever the preview shows unsupported sections.
• Material: PLA or Matte PLA for decorative indoor use. PETG is another option with suitable printer settings.
• Brim: Optional if the bases or tall sections need additional bed adhesion.
• Consistent Scaling: Apply the same scale factor to both cat sections for a coordinated appearance.
• Detail Check: When reducing the model, confirm that the ears, tail, legs, eye openings, and portal details remain printable.
• Finishing: Remove any supports carefully and smooth the bases and book-contact surfaces as needed.

These settings are suggested starting points, not verified print specifications for the supplied STL.
