What MeshySmith is

MeshySmith is a free browser and desktop 3D modeller for makers, classrooms, and prototyping. It runs on Linux, macOS, Windows, the web, and self-hosted installations. The editor provides 16 primitives across five categories, including gears, capsules, torus knots, and extruded text. Box edges can be filleted or chamfered with a smoothness control. Solid and hole boolean operations, including intersection, are powered by Manifold. STL meshes can be imported, while selected shapes or complete scenes export to STL or OBJ for 3D printing. A 26-zone ViewCube, perspective and orthographic views, and light, dark, and system themes are included. The maker describes the software as local-first: designs stay on the user’s machine and no sign-in is required. A Docker self-host bundle is offered for fab labs and classrooms. MeshySmith is open source under AGPL-3.0, with network-served modifications required to remain open. The project calls it alpha software and limits security fixes to the latest release on main.

Who it suits

Makers, classrooms, and prototyping users needing browser, desktop, or self-hosted modelling. It also suits people seeking local-first, open-source 3D design without an account.
