This model is a rope holder I printed for my family, measuring 25 x 15 x 17 mm.

It’s designed to securely hold a single M5 countersunk screw—both self-tapping screws and standard bolts are compatible, though countersunk screws are recommended for a cleaner, more aesthetically pleasing finish.

Key Features:

• Fast printing with minimal material consumption—just 4 g of filament is sufficient, making it an ideal way to use up leftover filaments.
• The design features two interlocking rings that require no supports during printing, offering greater convenience for secure attachment.
• Only a single screw is needed; the screw hole is centered, preventing rotational loosening under tension.
• An optimized structural design ensures high strength, even when printed in PLA, allowing for stable, long‑term use.
• A textured back surface enhances grip against walls, reducing the risk of rotation or slippage.
• Perfect for securing cords on vehicles, toys, tools, and various devices.
