Browser-based model import
Load STL, OBJ, GLB/glTF, or PLY files directly in the browser, including drag-and-drop input for quick testing.
BrickSolvr
BrickSolvr converts 3D models into stud-brick builds in the browser and creates a parts list for buying bricks. Supports STL, OBJ, GLB/glTF, and PLY.
Overview
BrickSolvr is a free, browser-based tool that converts 3D models into stud-brick builds. It supports STL, OBJ, GLB/glTF, and PLY files and shows the original model alongside the brick version in 3D.
The tool is designed to keep the workflow local: loading, voxelizing, and brick-building all happen in the browser, and the site says models are never uploaded. After conversion, BrickSolvr provides a parts list with brick sizes, colors, and quantities, plus a layer-by-layer guide for building the model in real life.
Core features
3D model-to-brick conversion
Convert the model into a stud-brick version and view the original and brick build side by side in 3D for comparison.
Size and color controls
Set a target model width in studs and cap the number of colors used so the result can trade off detail, size, and build complexity.
Buyable parts selection
Choose which brick sizes and colors are allowed, so the output better matches the parts you can actually buy or already own.
Parts list and CSV output
Generate an exact shopping list with brick sizes, colors, and quantities, along with a downloadable CSV export and warnings for missing or weak parts.
Step-by-step build guide
Follow a layer-by-layer build guide to assemble the model one layer at a time in 3D.
Common ways to use BrickSolvr
Prototype a physical brick build
Turn a personal or experimental 3D model into a brick-compatible version, then use the parts list to source the needed pieces.
Follow a guided build process
Import a model you want to assemble and use the build guide to follow the model layer by layer during construction.
Plan around your own parts inventory
Limit the color count and choose only the brick sizes you have on hand so the output better matches your existing collection.
Evaluate detail versus build size
Compare the original model and the converted brick version side by side to judge how much detail is preserved at a given size.
Prepare a purchase list
Use the downloadable CSV and exact part counts as a shopping reference before buying bricks for a build.
Pros and Cons
Pros
- Runs entirely in the browser, so models stay on the device.
- Supports multiple common 3D model formats, including STL, OBJ, GLB/glTF, and PLY.
- Shows the original model and the brick version side by side in 3D.
- Outputs an exact shopping list with brick sizes, colors, and quantities.
- Includes a layer-by-layer build guide and CSV download.
- Lets you limit colors and choose allowed brick sizes to better match real parts.
Cons
- Large models can take longer to process, especially on older devices.
- The page requires JavaScript and WebGL to run.
- The pricing page provided was not available, so no plan details or usage limits could be confirmed from that source.
FAQ
What file types can BrickSolvr convert?
BrickSolvr supports STL, OBJ, GLB/glTF, and PLY files. You can load a model in the browser by clicking the file picker or dropping a file onto the page.
Does BrickSolvr work locally or send files to the cloud?
BrickSolvr runs entirely in your browser and does not upload models to a server. JavaScript and WebGL must be enabled to use it.
What do you get after a model is converted?
BrickSolvr outputs an exact shopping list of brick sizes, colors, and quantities, and it also offers a downloadable CSV plus a layer-by-layer build guide.
Are there size or performance limits?
The homepage says larger models can take more computing power and may be slower on older devices. It also notes that a remote calculation option is coming later for bigger builds.
Is BrickSolvr built for team collaboration?
The site provides contact links for GitHub issue reports, email updates, and support email, but it does not show a team or multi-user collaboration workflow on the pages provided.
