CAD Skills
earthtojake
Open-source library of agent skills for CAD, robotics, fabrication, and simulation — generate STEP/STL, URDF/SRDF/SDF, DXF, and slicer G-code from prompts.
Key features
- Prompt-to-CAD Generation: The CAD skill creates and edits parametric CAD models from natural language or image requests, exporting to STEP, STL, 3MF, and GLB.
- URDF Robot Description: Writes robot structure files with links, joints, limits, inertials, and meshes ready for ROS-based stacks.
- SRDF for MoveIt2: Adds planning groups, end effectors, named poses, and collision rules on top of a URDF for MoveIt2 planning.
- SDF Simulation Worlds: Creates simulator models and worlds with frames, physics, sensors, and lights.
- 2D DXF Drawings: Produces cut-ready DXF profiles, templates, gaskets, and layouts from Python or CAD geometry.
- G-code Slicing: Slices supported mesh files into validated, printer-profiled FDM G-code using real slicer CLIs.
- Bambu Lab Print Jobs: Dry runs, uploads, and cautiously starts local Bambu Lab prints from validated G-code.
- CAD Viewer Previews: Local browser previews for CAD, G-code, URDF, and other robot files for fast agent iteration.
Best for
- Agentic Mechanical Design: Let a coding agent iterate on brackets, flanges, and enclosures directly from natural-language specs.
- Robot Description Authoring: Generate URDF/SRDF/SDF files for new robot arms or mobile bases without hand-writing XML.
- Rapid Prototyping: Take a CAD model to sliced, printer-ready G-code and kick off a Bambu Lab print from within an agent workflow.
- Custom Part Fabrication: Produce DXF/STEP files pre-checked for SendCutSend, then order laser-cut or CNC parts.
- Simulation Setup: Author SDF worlds for physics simulators with the right frames, sensors, and lighting for robotics research.
- Off-the-Shelf Sourcing: Use step.parts to pull ready-made STEP models for common hardware like screws, bearings, and connectors.
Shipper Advisor
Shipper.now
Create and launch complete apps by messaging an AI — no coding or design required; Shipper handles everything to deliver a live product.
Key features
- Conversational Product Specification: Lets users describe app ideas in natural language chat and converts those descriptions into concrete product specifications and tasks.
- Automatic UI & Design Generation: Produces user interface layouts, visual design choices, and interactive components without requiring manual design work from the user.
- End-to-End Implementation: Translates specifications into working frontend and backend components, generating the necessary code and configurations to create a functional application.
- One-Click Launch & Hosting: Handles app deployment and hosting so the generated product becomes a live, accessible application without separate infrastructure setup.
- Iterative Refinement via Chat: Supports multiple rounds of feedback and edits through the messaging interface so users can evolve features, flows, and visuals without coding.
- Productization Workflow: Manages the full productization pipeline (requirements → design → implementation → deployment), reducing friction for creating MVPs and prototypes.
- Build complete applications via natural-language messaging
- No-code app creation (claims no coding required)
- Automated design and implementation handled by the platform
- End-to-end productization from idea to live product
Best for
- MVP Creation for Founders: Non-technical founders can rapidly convert an idea described in chat into a live minimum viable product to test with users.
- Rapid Prototyping for Designers: Designers can get functional prototypes and clickable UIs from descriptions to validate interaction concepts without hand-coding.
- Product Team Exploration: Product managers can iterate on feature ideas and get working demos to align stakeholders and collect feedback faster.
- Side-Project Launches: Builders and hobbyists can launch simple web apps or tools by describing functionality rather than writing code and configuring infrastructure.
- Client Demos and Proofs-of-Concept: Agencies and consultants can produce quick, demo-ready applications for pitches and client validation.
- Feature Iteration and Bug Fixes: Teams can request changes or fixes through chat and receive updated, redeployed application versions without manual developer intervention.
- Convert an idea into a live product through chat-based instructions
- Rapid MVP creation for non-technical founders or teams
- Prototype and iterate product concepts without coding or design resources
