A project published on sael.net presents interactive 3D versions of IKEA’s BILLY bookcase and LACK side table assembly instructions. It follows the manuals’ parts, hardware counts and assembly order, while warning that some dimensions are estimated and the project is not made or endorsed by IKEA.
Sael.net has published an interactive 3D assembly guide for two IKEA products, the BILLY bookcase and LACK side table, translating their instruction manuals into step-by-step digital builds. The project follows the manuals’ parts, hardware counts and assembly order, but says some physical measurements are estimated and that it is not made or endorsed by IKEA.
The BILLY model is based on the 80 × 28 × 202 cm bookcase and IKEA assembly manual AA-1823127-9. The guide presents the manual alongside the build and lets users move between steps with arrows or a timeline, play the sequence, inspect parts and switch to a drawing view styled after the manual. A part can also be selected to display its name and number.
The project lists 82 hardware pieces for the BILLY build: 16 wooden dowels, 12 cam screws, 12 cam locks, 18 nails, 16 shelf pins, plus two wall brackets, two screws and four washers. It describes the assembly as two side panels, top and bottom panels, a fixed middle shelf, a plinth, four loose shelves and a back panel folded in three. The guide’s hardware count tracks pieces as they are added.
Users can switch to the 55 × 55 × 45 cm LACK side table, based on manual AA-2606170-1. Its assembly is shown as four double-ended screws, identified as part 115980, and four legs. Sael.net says the manual ends after the legs are attached, while the 3D guide adds a third step to turn the table over.
A Visual Route Through Assembly
The guide gives users another way to follow instructions that are normally presented as static drawings. Seeing parts move into place, and being able to pause, replay or jump between steps, may help some builders understand how components relate before handling them. The project also explains the BILLY’s cam-lock connection: a cam screw’s head enters a round cam, and turning the cam draws the panels together. The guide says dowels align the panels, while the cams provide the clamping force.
That visual aid does not replace the manufacturer’s safety instructions. The project notes that the BILLY manual calls for two people when lifting or turning the assembled case and warns that a bookcase tipping over can cause fatal injuries. It says to secure the unit to the wall using the brackets, with suitable wall screws and plugs selected for the specific wall; those fasteners are not included. The safety point matters because the guide’s accelerated animation can make assembly look easier or quicker than it is in real conditions.

Manuals Behind the Models
Sael.net says the BILLY sequence was built from IKEA manual AA-1823127-9, reproduced alongside the 3D model page for page. It identifies manual AA-2606170-1 as the source for the LACK table. The project states that the product parts, hardware counts and assembly order come from the manuals, while the bookcase’s overall dimensions are based on IKEA’s published measurements.
There is a distinction between following the diagrams and measuring a real product. According to the project, panel thickness, hole positions and shelf heights were estimated from the drawings and are close, not measured. It also says the simulation runs much faster than a person assembling the furniture. The page credits the manual to Inter IKEA Systems B.V. and says it is reproduced unaltered; it identifies IKEA and BILLY as trademarks and disclaims any IKEA endorsement.
“The parts, counts, order and hardware numbers are the manual’s.”

Limits of the 3D Measurements
The source does not provide independent testing of the guide’s accuracy or say whether IKEA reviewed it. While the assembly order and hardware counts are described as matching the manuals, some model dimensions are inferred from illustrations rather than measured from the furniture. The guide should therefore be treated as a visual companion, not as a replacement for the manufacturer’s instructions.
It is also unclear from the source when the guide was first published, whether more products will be added, or whether future updates are planned. No information is given about how the model handles variations between product versions or changes to assembly manuals.
Use the Official Manual Too
For anyone assembling either item, the practical next step is to consult the matching IKEA manual and use the 3D page as an additional visual reference. BILLY builders should follow the manual’s two-person lifting guidance and attach the bookcase to the wall with fasteners appropriate for its construction. Sael.net does not announce a release schedule or further product additions, so any expansion of the guide remains unconfirmed.
Key Questions
What does the IKEA 3D Guide cover?
It presents interactive assembly sequences for the BILLY bookcase and LACK side table, based on their IKEA manuals.
Is the guide an official IKEA product?
No. Sael.net says the project is not made or endorsed by IKEA. It reproduces the manual alongside the digital build and identifies IKEA and BILLY as trademarks of Inter IKEA Systems B.V.
Are all dimensions in the BILLY model exact?
No. The overall dimensions come from the published 80 × 28 × 202 cm size, but the project says panel thickness, hole positions and shelf heights are estimated from drawings rather than measured.
Does the guide replace the IKEA assembly manual?
No. It is a visual companion. Users should follow the official manual, including its safety directions, lifting guidance and wall-anchoring instructions.
What safety warning applies to the BILLY bookcase?
The project says the manual warns that a tipping bookcase can cause fatal injuries. It calls for securing the unit to the wall and notes that suitable wall screws and plugs depend on the wall and are not included.
