Designed specifically for one standard 31.5 in / 80 cm wide IKEA BILLY bookcase. A modular crown kit for a built-in appearance without permanently modifying your furniture.
The modular 3D-printed crown pieces for one wide bookcase, including Left and Right Wall Ends. Use the appropriate included end if the bookcase stands against a wall. Furniture is not included.
Easy DIY installation with no glue or screws required. Measure the outside width before ordering. For connected bookcases or mixed sizes, choose the main Crown Molding Kit instead.
For standard BILLY bookcases approximately 11 in / 28 cm deep. Some models are 15⅜ in / 39 cm deep: contact us before ordering if yours is not 28 cm deep. Measure the full outside width and make sure all connected bookcases are level and the same height.
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.
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.
