LANDING

/// OPEN ENGINEERING · EST. 2026

Big engineering projects. Real teams. Real prototypes.

An open source design competition for projects that take a team, real engineering skill, and funding to actually build, not something one person finishes in a weekend. The community votes and improves the designs, and the best ones get built for real.

OPEN SOURCE

FIG. 01 — HYDROWHEEL / ASSEMBLY · REV A, CAD NOT FINAL

SEC. 01 — HOW IT WORKS

Every project breaks into components. Every component runs sprints. Every design moves through the same three stages, driven by the community, not a single judge's opinion.

THREE STAGES

01 / ConceptRough first pass; weeded out fast if it isn't working

02 / RefinedCommunity has converged; details locking in

03 / Build-ReadyDetailed enough to hand to a fabricator
