Manta Ray Book Holder - Elegance and Functionality Inspired by the Manta Ray

The Manta Ray Book Holder is an elegant and functional reading accessory designed for those who love to read with just one hand.
Its flowing, organic shape is inspired by the Manta Ray - a symbol of grace and lightness - blending aesthetics and practicality in a print that’s fast, useful, and beautiful.
The central 24.5 mm ring is ergonomically designed to fit both large and small hands comfortably, offering a secure yet relaxed grip for long reading sessions.
The project includes four variants, each tailored to different needs:
- Light Version (3 walls, hollow) - the simplest and fastest one: under 10 minutes of print time and only 5 g of filament. Perfect for a quick, minimal result. Because of its open geometry, it flexes slightly, but that’s a small price to pay for such a sleek, distinctive design.
- Gyroid Version (15% infill) - my favorite! The gyroid infill adds a stunning internal pattern while enhancing strength without significantly increasing print time.
- 3D Honeycomb Version - features a geometric diamond-like structure for a unique and decorative look.
- Solid Version (closed top & bottom) - the strongest, perfect for larger or heavier books.
All four variants deliver style, comfort, and lightness, making them perfect last-minute Christmas gifts for book lovers who enjoy reading in total relaxation.
📖 A small print with big personality.
Note: While the print is straightforward, it’s advisable to thoroughly clean the PEI bed and handle it without direct contact from your fingers.
