TL;DR
A project described by sael.net presents interactive 3D builds for IKEA’s BILLY bookcase and LACK side table, following the products’ assembly manuals step by step. It reproduces parts, hardware counts and assembly order, but some dimensions are estimates rather than measurements, and the site says it 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, recreating the steps and hardware shown in each product’s manual. The guide gives readers a way to inspect parts and follow assembly digitally, but its creator says some dimensions and hole positions are approximations and that the project 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. According to the project description, the 3D build follows the manual’s parts, hardware counts and sequence, presenting each step from an angle similar to the corresponding drawing. Users can move through steps with arrows or a timeline, play an individual step, or compare the 3D build with the manual displayed beside it.
The guide lists 82 pieces of hardware for the BILLY build: 16 wooden dowels, 12 cam screws, 12 cam locks, 18 nails, 16 shelf pins, two wall brackets, two screws and four washers. It also models the bookcase’s panels, shelves and folded back panel. A user can select a part to hear its name and number, switch between a room view and a drawing-style view, or expand the model into an exploded view.
A second model covers the 55 × 55 × 45 cm LACK side table, using manual AA-2606170-1. The project describes its build as four legs attached by four double-ended screws, part number 115980. The manual ends after the legs are attached; the 3D guide adds a third step to show the table being turned over. The site says its manual reproductions are unaltered and identifies the manuals as IKEA material, while stating that the project itself is independent.
A Digital View of Each Assembly Step
The guide addresses a practical limitation of paper assembly instructions: a fixed drawing can be difficult to interpret when parts, fasteners or orientation are unfamiliar. Here, users can advance through a build, inspect the model and identify components, which may help them understand how a step relates to the finished item. The side-by-side manual view also links the digital recreation to the source instructions rather than presenting it as a replacement with a separate sequence.
The BILLY example makes the distinction between alignment and fastening visible. The project explains that dowels align the boards while cam locks clamp them together; it also describes the nailed back panel as the part that keeps the case square. That added visual explanation could be useful to someone trying to understand why a particular fitting or board is needed, though the source material does not report user testing or show that the guide reduces assembly errors.
Safety remains relevant, especially for a tall bookcase. The project repeats the manual’s warning about tip-over risk and says the case should be fixed to the wall with the supplied brackets. It notes that wall screws and plugs are not included because the appropriate fixings depend on the wall. Readers should follow the product manual and choose suitable fixings for their wall rather than treating the animation as a substitute for safe installation.

Manuals Behind the 3D Models
The guide is a digital interpretation of two specific IKEA products, not a general assembly service for the company’s furniture range. For BILLY, its stated source is manual AA-1823127-9; for LACK, it is AA-2606170-1. The project says the parts, counts, hardware numbers and order come from those manuals. It also provides controls for stepping through the build, playing it, resetting the view and moving around the model.
There is an important limit to the models’ precision. The BILLY’s published overall dimensions are given as 80 × 28 × 202 cm, but the project says panel thicknesses, hole positions and shelf heights were inferred from drawings and are “close, not measured.” It also says the animation runs much faster than assembly by hand. The guide’s stated purpose is to show the sequence and parts; the source does not claim that its geometry is a manufacturing-accurate or independently tested digital replica.
“The parts, counts, order and hardware numbers are the manual’s.”

Model Accuracy and IKEA’s Role
The source does not state when the guide was published, whether IKEA reviewed it, or whether the company has commented. The project explicitly says it is not made or endorsed by IKEA. It also does not provide measured specifications for panel thickness, hole locations or shelf heights, and no independent evaluation of the model’s accuracy is included. The source gives no evidence about how users have responded or whether additional products will be added.
Use the Guide Alongside the Manual
Readers using the guide can move through the steps, compare them with the corresponding IKEA manual and use the model to inspect part placement. For the BILLY, the source says to follow the manual’s safety instructions, including securing the bookcase to the wall. Because the guide acknowledges estimated measurements and faster-than-real-time animation, the product manual should remain the reference for actual assembly. The source material does not announce a release schedule for further models or other updates.
Key Questions
Which IKEA products are included in the 3D guide?
The project includes an 80 × 28 × 202 cm BILLY bookcase and a 55 × 55 × 45 cm LACK side table, each modeled from its own IKEA assembly manual.
Does the 3D guide replace IKEA’s instructions?
No. The project follows the manuals’ assembly order and offers a side-by-side manual view. Its description does not say it replaces the instructions; users should consult the original product manual when assembling the furniture.
Are all dimensions in the BILLY model exact?
No. The project says the overall published dimensions are used, while panel thicknesses, hole positions and shelf heights are inferred from drawings and are close estimates, not measurements.
Is the guide officially affiliated with IKEA?
The project says it is not made or endorsed by IKEA. It identifies the manuals as IKEA material and says they are reproduced unaltered.
Does the guide include a warning about securing BILLY?
Yes. It repeats the manual’s tip-over warning and says the bookcase should be fixed to the wall. Wall screws and plugs are not included, as the suitable fixings depend on the wall.
