The official Open-Asset-Importer-Library Repository. Loads 40+ 3D-file-formats into one unified and clean data structure.

JSCAD is an open source set of modular, browser and command line tools for creating parametric 2D and 3D designs with JavaScript code. It provides a quick, precise and reproducible method for generating 3D models, and is especially useful for creating ready-to-print 3D designs.

A simple CAD package using signed distance functions

A physics-based multi-material FDM color system. Converts images to full-color 3D prints via calibrated light-transmission mixing. Supports 2-8 color systems with slicer-ready 3MF export (BambuStudio/OrcaSlicer).

Connects MCP to major 3D printer APIs (Orca, Bambu, OctoPrint, Klipper, Duet, Repetier, Prusa, Creality). Control prints, monitor status, and perform advanced STL operations like scaling, rotation, sectional editing, and base extension. Includes slicing and visualization.
