BILLY Crown 90° Corner Connectors

An add-on for your crown kit

Complete a 90° BILLY corner setup with two magnetic, 3D-printed pieces per corner. Choose one corner (2 pieces) or two corners (4 pieces). The FURNIX3D crown molding kit is sold separately.

Secure the bookcases first

Bookcases must already be fully assembled, level, wall-anchored and firmly connected in their final 90° position using appropriate corner hardware. These decorative connectors do not position, support, secure or stabilize furniture.

Installation

Place one connector piece on each adjoining bookcase, then align the magnetic joint by hand. Magnets help align the molding pieces only; they do not pull the bookcases tightly together. A fine connection line is normal; uneven bookcases can cause a wider seam or step.

Connectors only

Includes the selected corner connectors. Bookcases, crown molding, corner hardware and décor are not included. Use the BILLY Crown Molding planner to preview a 45° or 90° corner layout.

Material & colour

Made from solid-colour matte PLA using 3D printing. Fine layer lines, small seams and minor surface variations may be visible. Dark Brown and Light Beige are coordinating solid colours, without wood grain. An exact match to IKEA furniture is not guaranteed; colours vary with lighting, screens and furniture batches.

An independent accessory

Designed by FURNIX3D, not made by, sponsored by or affiliated with IKEA. IKEA, BILLY and KALLAX names describe compatibility only. Furniture, original hardware and decorative items are not included.
