dsh-print3d

Running a full 3D-printing workflow inside an agent conversation—parametric modeling, calibration G-code, slicing estimates, toolpath inspection—normally means hand-cranking scripts, flipping through material parameter sheets, and stuffing megabytes of G-code text into the context window until a 7B model loses the thread. dsh-print3d turns every step into six first-class agent tools and five on-demand knowledge skills. Generated STL, G-code, and PNG files are written straight to a local output folder and only the file path is returned to the model, keeping the context lean enough for small local models to stay on task end to end.

The tool layer covers parametric STL generation (box, cylinder, tube, sphere, cone, rounded box, and gear), five categories of calibration-part G-code (cube, temp-tower, first-layer, retraction, bridge), STL watertightness and overhang analysis, G-code print-time and material estimation, toolpath top-down PNG rendering, and an optional bridge to a local PrusaSlicer install. The skill layer structures engineering knowledge—twelve material parameter tables, Marlin vs. Klipper dialect differences, STL and G-code metric interpretation, and a ten-fault diagnostic matrix—so the agent loads exactly the reference it needs via tool-skill without bloating the system prompt.

The plugin is preset-agnostic: any DSH agent, regardless of persona, can call the print3d tools and load the print3d skills out of the box with zero extra npm dependencies. It is especially well suited to users running local small models such as Ollama + Qwen3 8B, where the bundled concise persona is tuned for short-instruction prompting and the entire model, estimate, and diagnose cycle runs offline with no API cost.
