A project published on sael.net presents interactive 3D assembly guides for IKEA’s BILLY bookcase and LACK side table, following the steps and hardware counts in their manuals. The creator says some dimensions are estimated from drawings, and the guide is not made or endorsed by IKEA.
Sael.net has published an interactive 3D assembly guide for IKEA’s BILLY bookcase and LACK side table, translating the products’ instruction manuals into step-by-step digital builds. The project follows the manuals’ parts, hardware counts and assembly order, but says some measurements are estimates and the guide is not made or endorsed by IKEA.
The BILLY guide covers the 80 × 28 × 202 cm bookcase and says it is built from IKEA manual AA-1823127-9. Users can advance through the steps with arrows or a timeline, or play an animation. The project also lets readers display the manual beside the 3D model, click a drawing to jump to its corresponding step, and select parts to hear their names and numbers.
According to sael.net, the BILLY build includes two side panels, a top and bottom, a fixed middle shelf, a plinth, four adjustable shelves and a back panel folded in three. It lists 82 hardware pieces: 16 wooden dowels, 12 cam screws, 12 cam locks, 18 nails, 16 shelf pins, and wall-fixing hardware consisting of two brackets, two screws and four washers. The guide tracks the hardware as it is added.
A second mode covers the 55 × 55 × 45 cm LACK side table, using manual AA-2606170-1. The source describes its assembly as four double-ended screws, part number 115980, and four legs, installed by hand. It adds a third 3D step to show the table being turned over, an action the manual leaves to the user after attaching the legs.
A Manual Shown as a 3D Build
The guide offers another way to follow furniture assembly instructions: instead of interpreting each flat drawing alone, users can watch the parts come together and compare the model with the original manual. Showing the hardware count and how each piece is used may help readers understand the sequence, particularly for a build involving many components.
It also explains a key part of the BILLY’s construction. The project says the cam locks clamp the panels together, while wooden dowels align them; the nailed back panel helps keep the case square. This is presented as an explanation of the assembly shown in the manual, not as a substitute for following its instructions or safety warnings.
The guide’s limits matter as much as its interactive features. Because some dimensions and positions are inferred rather than measured, users should treat it as a visual aid, not a precision model. The project itself says the animation moves faster than real assembly and notes that the manual calls for two people when lifting or turning the full bookcase.

The Manuals Behind the Models
Sael.net says the BILLY model follows IKEA manual AA-1823127-9 page by page, using the same parts, hardware quantities and sequence. The LACK mode is based on manual AA-2606170-1. The project says the BILLY manual is reproduced unaltered and identifies IKEA and BILLY as trademarks of Inter IKEA Systems B.V.; it also states that the project is independent and not endorsed by IKEA.
The source distinguishes between details taken directly from the manuals and dimensions inferred for the 3D model. Parts, counts, order and hardware numbers come from the manuals. The bookcase’s overall dimensions are given as published product dimensions, while panel thickness, hole positions and shelf heights are read from illustrations and described as close, not measured.
“The parts, counts, order and hardware numbers are the manual’s.”

Estimated Dimensions and Safety
The source does not provide independent verification of the 3D models or measurements. It expressly says that panel thickness, hole locations and shelf heights are estimated from drawings, rather than measured from the products. It also does not give a publication date, explain how the models were tested against physical furniture, or say whether additional products will be added.
For safe assembly, the project points readers back to the manual. It says the manual warns that a tipping bookcase can cause fatal injury and directs users to secure the BILLY to a wall using the brackets shown in step 12. Wall screws and plugs are not included, because the appropriate fixings depend on the wall. The source does not specify which fixings suit each wall type; users should follow the product instructions and seek appropriate advice if uncertain.
Following the Build Instructions
The project currently describes controls for stepping through or playing the BILLY and LACK builds, changing between a room view and a drawing, and viewing an exploded model. It does not announce a release schedule, further IKEA products or planned updates. Readers can consult the original IKEA manuals alongside the 3D guide; for the BILLY bookcase, the source specifically says to use two people for steps that require lifting or turning the full case and to attach the unit to the wall as directed.
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 respective IKEA manuals.
Is the 3D guide an official IKEA product?
No. Sael.net says the project is not made or endorsed by IKEA. It identifies the IKEA manuals as the source for the assembly steps.
Are all measurements in the BILLY model exact?
No. The source gives the bookcase’s published overall dimensions, but says panel thickness, hole positions and shelf heights are estimated from manual drawings and are not measured.
Does the guide replace the BILLY manual’s wall-fixing instructions?
No. The project says to fix the bookcase to the wall and notes that the required wall screws and plugs depend on the wall and are not included. Users should follow the original manual’s safety directions.
