dsh-print3d: A 3D Printing Capability Plugin for DeepSeek Harness

`dsh-print3d` is a 3D printing plugin for DeepSeek Harness (DSH), centered on the philosophy of “everything is a plugin.” It provides six model tools—including parametric STL generation, calibration G-code generation, STL/G-code analysis, and slicing—and five Markdown knowledge packs covering skills such as slicing and diagnostics to encapsulate workflows for modeling, calibration, analysis, and troubleshooting. The plugin supports parametric geometry generation, STL watertightness checking, toolpath visualization, and PrusaSlicer slicing, and can be invoked directly by Agents after installation. Users should observe high-temperature safety precautions and manually verify parameters before delivery to ensure compliant operation.
