Existing CAD applications, scripts and workflows can often be migrated with minimal modifications, making GstarCAD an ideal platform for organizations that depe
Description
OwlCAD is a browser-based parametric CAD editor aimed squarely at 3D printing, giving hobbyists and makers real engineering tools without installing software or buying a professional license.
Designs are driven by dimensions you can revisit at any time; edit a number and the part updates. Solids combine cleanly, fit presets (press, slip, loose) account for FDM tolerances, and a print check points out overhangs, walls too thin to print and open meshes before anything reaches your slicer. Hollowing, lay-flat orientation and print weight and cost estimates help you prepare the part itself.
The toolset covers constrained 2D sketches, fillets and chamfers on individual edges, sweeps, lofts, patterns, datum planes, measurement, and assemblies with mates, an exploded view and a parts list. More than 30 generators build gears, threads, enclosures, hinges and Gridfinity storage. Bring in STEP, STL, 3MF, OBJ or OpenSCAD files; send out STEP, STL, 3MF, OBJ, GLB, DXF or SVG.
Your work autosaves locally and syncs to cloud projects with version history and share links. You can also publish a customizable model that others adjust and download. Whatever you design is yours to sell, prints and files alike, on every plan.
The editor is free. A Pro subscription adds AI that drafts either an editable parametric model or a sculpted mesh from a prompt, AI-assisted edits, and an MCP server so agents such as Claude Code or Cursor can model on your account. Pro users can bring their own provider key and skip credits. A desktop app is available too.
Open it and start designing; signing up is optional.

You keep full commercial rights to anything you design, on every plan.
Pro is $12 per month, or $120 per year (two months free). It adds AI generation across several models, Modify-with-AI, AI-assisted customizing, and MCP access for AI agents. Pro includes 20 AI credits a month, which reset monthly. Light parametric generations cost one credit, and detailed mesh models cost a few. One-time credit top-up packs never expire. Pro users can also bring their own AI provider key and generate without spending credits. Payments are handled by Stripe, and you can cancel anytime with no contract.
Classroom features for K-12 schools are free. Districts can add a pooled AI credit budget for teachers; contact OwlCAD for details.
