TL;DR
Sael.net has published an interactive 3D guide that presents the IKEA BILLY bookcase assembly manual as a navigable model, with steps, parts and hardware based on the manual. The site says some model details are estimated from drawings and warns users to follow IKEA’s safety instructions, including securing the bookcase to a wall.
Sael.net has published an interactive 3D guide that walks users through assembling an IKEA BILLY bookcase, translating the product’s printed manual into a model that can be rotated, explored and advanced step by step. The project uses IKEA manual details for its parts and assembly sequence, but the site says some dimensions and construction details are approximations rather than manufacturer-verified specifications.
The guide lets users move through the build with arrows or a timeline, play the sequence, and open the manual alongside the model. Selecting a drawing jumps to its corresponding step, while clicking a component identifies it. Users can also switch between a room view and a line-drawing style, pull the model apart, or change to another supported piece through the guide’s controls.
For the BILLY model, the page lists two sides, a top, a bottom, a fixed shelf, a plinth, four shelves and a folded back. It also identifies 82 hardware pieces: 16 dowels, 12 cam screws, 12 cam locks, 18 nails, 16 shelf pins and two wall brackets with screws and washers. The guide explains how a cam lock turns to draw a cam screw inward and clamp boards together; dowels help align the boards, while the nailed back helps keep the unit square.
Sael.net says the parts, part numbers and step order are taken from the IKEA manual and gives the bookcase size as 80 × 28 × 202 centimetres. It cautions that board thickness, hole locations and shelf heights were estimated by eye from the manual’s drawings. The page says the manuals are reproduced unaltered, links each manual header to the relevant IKEA page, and states that sael.net is not affiliated with or endorsed by IKEA.
A Visual Layer for Flat-Pack Instructions
The guide offers another way to follow a familiar assembly process, particularly for users who find it difficult to interpret flat, static diagrams. Rotating the model and identifying individual parts may help clarify how components fit together and where a step sits in the overall build. The site’s controls also let users revisit earlier steps rather than relying only on a linear sequence.
That convenience comes with a distinction readers should keep in mind: the interactive model is not presented as an IKEA-built or IKEA-endorsed product. The guide draws on the company’s manual for its sequence and component information, but some geometry was estimated. For actual assembly, IKEA’s original instructions remain the reference, especially for safety warnings and wall fixing. A visual aid should not be treated as confirmation that an estimated measurement or model detail is exact.
The safety information has direct practical importance. The guide repeats the manual’s warning that a bookcase can cause fatal injuries if it tips over and identifies the included wall brackets as part of the prescribed assembly. It also says wall screws are not supplied because the correct fasteners depend on the wall. That means the guide cannot identify a universal screw choice for every home.

What the Guide Uses from IKEA
The source report describes the project as an interactive presentation of IKEA’s BILLY assembly manual, not a change to the bookcase itself or an announcement from IKEA. Its content tracks the manual’s parts and step order, and the reproduced manual pages link to IKEA’s own product-manual page. Sael.net also lists keyboard and mouse controls for moving through the guide, rotating and panning the model, changing the view, and opening the manual.
The guide’s own accuracy note sets the boundary between sourced information and visual interpretation. The listed dimensions are given as 80 × 28 × 202 centimetres, while board thickness, hole positions and shelf heights are described as estimates based on drawings. The source report does not provide an independent technical review or say that IKEA checked the digital model. It also does not give a publication date, user figures or evidence that the guide has been adopted by the company.
“The parts, part numbers and order of steps come from the manual.”

Model Accuracy and IKEA Involvement
The source material does not state whether IKEA reviewed, approved or tested the 3D model. Sael.net explicitly says it is not affiliated with or endorsed by IKEA, and the report provides no evidence of company involvement. The extent to which the estimated board thickness, holes and shelf heights differ from the physical product is also not specified.
It is also unclear when the guide was published, which other IKEA products are currently available in it, or whether additional models are planned. The page says users can select other pieces and that each follows its own IKEA manual, but the source does not provide a full catalogue or describe how often the guides are updated. No usage data or testing results are included.

Use the Manual for Assembly
Users can open the linked IKEA manual beside the model and follow the source instructions as they work. The guide advises getting a second person when lifting or turning the whole bookcase and reiterates that the unit should be fixed to the wall. Because the correct wall screws depend on the wall and are not included, users should select suitable fasteners for their specific surface rather than assuming the model specifies them.
Sael.net’s page does not announce a release schedule or a next product guide. Any expansion of the project, changes to the model, or response from IKEA remains unreported in the source material. For now, the confirmed development is the availability of the interactive guide and its linked manual—not an official change to IKEA’s assembly instructions.

Key Questions
What is the IKEA 3D Guide?
It is an interactive sael.net presentation of the IKEA BILLY assembly manual, with a model users can rotate and advance through the build step by step.
Is the guide an official IKEA product?
No. Sael.net says it is not affiliated with or endorsed by IKEA. The page reproduces manuals unaltered and links to the original IKEA manual.
How accurate is the 3D model?
The guide says its parts, part numbers and assembly order come from the manual, and lists the bookcase as 80 × 28 × 202 centimetres. It says board thickness, hole positions and shelf heights were estimated from drawings.
Does the guide replace the IKEA manual?
The source does not say that it replaces the manual. Users can open the linked manual alongside the 3D view; the manual remains the source for the assembly sequence and safety directions.
What safety instructions does the guide highlight?
It repeats the manual’s warning about tip-over danger, says to use the wall brackets, and recommends a second person when lifting or turning the case. Wall screws are not included because the suitable choice depends on the wall.
