Brickify is a web-based tool that helps users create custom 3D-printed parts designed to work with LEGO bricks, making prototyping and model building more flexible. Users can upload an STL file, customize a model, or explore example designs, then download files for 3D printing. The service also provides LEGO building instructions and SCAD files for supported models.

Because 3D printers can produce parts at slightly different sizes, Brickify includes a calibration process to help users achieve a better fit with their LEGO bricks. It guides users through downloading and printing a test strip, checking how its studs connect with a LEGO brick, and saving suitable printer settings for future prints. A wizard can help identify a printer type when users are unsure.
