Design, edit, and prepare 3D models for printing directly on your phone or tablet — or simply tell the AI agent what you need and watch it build the model for you. 3D Model Print Simple Edit is a fast 3D editor designed for touchscreens, makers, and 3D printing enthusiasts. No desktop CAD and no steep learning curve: shape your ideas and send them directly to your 3D printer. LET AI BUILD IT — MCP INTEGRATION Connect Claude, Gemini, or any AI agent that supports the Model Context Protocol (MCP). Generate a key in the app, paste it into your AI agent, and describe what you need: “a chair,” “a phone stand,” or “a box with a lid.” The agent creates and edits real objects directly in your scene while you watch it work. Then refine, sculpt, and paint the result by hand. Go from a single sentence to a print-ready model in just a few minutes. SCULPTING Push, pull, inflate, and smooth surfaces with intuitive sculpting brushes. Turn simple shapes into organic forms in seconds. CSG BOOLEAN OPERATIONS Union, subtract, and intersect objects to cut holes, merge parts, and build complex mechanical shapes from simple blocks. POWERFUL MODIFIERS • Twist objects into spirals and decorative shapes • Round edges to create smooth, print-friendly corners • Flip and mirror parts with a single tap • Draw your own shapes and turn them into 3D objects FULL-COLOR PAINTING Paint your models and prepare them for multicolor 3D printing. 3MF EXPORT WITH PLATES Arrange objects on build plates and export them as 3MF files — ready to open in your slicer. BUILT FOR TOUCH • Hide side panels for a full-screen workspace • Rename and organize objects directly from the hierarchy • Built-in help with short videos for every tool • Works great on both phones and tablets WHO IS IT FOR? • 3D printing hobbyists who want to modify models on the go • Makers who need a custom part, bracket, or replacement part quickly • Beginners who want to create without learning complicated CAD software • Anyone curious to see how AI can design real, printable objects Download 3D Model Print Simple Edit and turn your ideas — or your prompts — into real-world objects.
