A made-to-order modular crown kit for 2–6 connected standard-width BILLY bookcases, approximately 80 cm / 31.5 in wide each. This listing is not for narrow or mixed wide/narrow layouts; use the main Crown Molding Kit for those.
Crown molding sections for your selected configuration, required connecting components, both Left and Right Wall Ends, and an illustrated installation guide. Bookcases and décor are not included.
Work from one side to the other along the top shelf. Position each section, connect adjoining pieces and align them by hand. No woodworking required. Fine joint lines may remain visible.
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.
