VNF Export Extension earns its place for doing one job cleanly: moving Blender mesh geometry into OpenSCAD as a VNF. Its 14.1 KB footprint and single file-export permission keep it lean, and the developer's note on checking face orientation reflects attention to how the result behaves in OpenSCAD.
VNF Export Extension is a Blender add-on from runerback that exports mesh geometry to OpenSCAD VNF, a module built with BOSL2. It writes .scad files to disk, and the developer describes version 1.0.0 as straightforward exporting. The extension requests a single permission: exporting .scad to disk.
It is compatible with Blender 4.2 LTS and newer, with builds for Windows and Linux, and the download is a compact 14.1 KB package. Installation works either by dragging and dropping the extension into Blender or by downloading the package and using Install from Disk. The add-on is released under the GNU General Public License v3.0 or later, and it ranks 744 on the Blender extensions platform.
The developer also notes a practical detail for working with the result in OpenSCAD: face orientation matters when building a polyhedron or VNF. Selecting View → Thrown Together shows any reversed faces in purple, which need fixing before the geometry is correct. Source and issue tracking are hosted on the developer's GitHub page.
VNF Export Extension is best for blender users who need to export mesh geometry to OpenSCAD as a VNF module built with BOSL2.
VNF Export Extension is completely free to download and use.
VNF Export Extension lists compatibility with Blender 4.2 LTS and newer, so it runs on the current LTS line and later releases. It is available for Windows and Linux, and the download is a compact 14.1 KB package. The add-on requests a single permission, writing .scad files to disk, which it uses to save the exported OpenSCAD VNF. Version 1.0.0 was published in October 2025. If you run an older Blender build, check the developer's GitHub page before installing to confirm the version you have meets the stated minimum.
VNF Export Extension installs two ways in Blender. You can drag and drop the extension into Blender, or download the package and use Install from Disk through the extensions preferences. The download is a compact 14.1 KB file covering the Windows and Linux builds. Once installed, the add-on provides export functionality for writing Blender mesh geometry out as an OpenSCAD VNF module. Full instructions and the source live on the developer's GitHub page, which is also the best place to check setup details and report any issues you run into.
VNF Export Extension writes .scad files to disk, exporting Blender mesh geometry as an OpenSCAD VNF module built with BOSL2. The permission it requests is limited to exporting .scad to disk. Version 1.0.0 describes the workflow as straightforward exporting. When working with the result in OpenSCAD, the developer notes that face orientation matters: you can use View → Thrown Together to spot reversed faces, which appear purple and need fixing before the polyhedron or VNF is correct. Source and issue tracking are on the developer's GitHub page.
VNF Export Extension is listed as free here in the catalog, and it is released under the GNU General Public License v3.0 or later. That license governs how you can use, modify, and redistribute the add-on. For current licensing terms and any changes, check the developer's GitHub page. The extension is a compact download available for Windows and Linux, and it has been downloaded over a thousand times on the Blender extensions platform since its October 2025 release. Version history and source are available from the developer directly.
