I made a free, open-source GH plugin for Rhino 8: tetrahedral lattices, adaptive remeshing, PDF layout, and data and export utilities (Mac + Windows)
Hey all
I've been building this for the past year and just released it on Package Manager and food4rhino: Slicelab Tools. It's a GH plugin for Rhino 8. It's free, open source (AGPL), and runs on both macOS (Apple Silicon native) and Windows.
It started because I do a lot of 3D printing work and kept hitting the same walls: no good way to generate tetrahedral lattices without leaving Grasshopper or only on Windows with very limited tools, and no PDF layout at all on Mac. So I built the tools I wanted:
- Tetrahedralize + 10 lattice generators: turn any closed mesh into tetrahedra, then swap between 10 lattice topologies (vertex/midpoint/face-center networks, edge lattices, Voronoi dual). Pipe the struts into Dendro for a printable volume.
- Adaptive TriRemesh: triangular remesh with feature curves/points embedded in the output topology + attractor-driven density
- Mesh Operations: Manifold mesh booleans, plus repair/refine/decimate nodes
- PDF layout: composable multi-page documents (nothing fancy) straight from GH (text, images, Make2D linework, viewport captures). Mac users: this one's for you.
- Export: fast binary STL, 3MF with metadata, GLB with Draco compression
Install: Rhino 8 Package Manager → search SlicelabTools. (Windows: Rhino needs the NETCore runtime — run SetDotNetRuntime, pick NETCore, restart.)

I'm the author, happy to answer anything. If you try it and something breaks, please let me know, this is one of the main reasons for posting it here.
Thanks
