3D Tools
Free browser-based 3D tools for 3D printing, modeling, and design. View STL files, convert between 3D formats, estimate printing costs and time, generate 3D text, and create product mockups — all without installing software. Everything runs locally in your browser.
AI 3D Prompt Generator
Generate optimized prompts for Hyper3D, Meshy, and Tripo3D. Choose style, material, and platform — powered by in-browser AI.
3D Model Viewer
Open GLB, GLTF, OBJ, STL, FBX, 3DS, and PLY files in a free 3D model viewer online. Rotate, zoom, wireframe, and screenshot privately.
WebGL Fluid Simulation
Interactive fluid dynamics — click, drag, and create mesmerizing colorful patterns with real-time physics.
3D Audio Visualizer
Upload music and watch stunning 3D visuals react to the beat. Bars, sphere, waveform, and particle modes.
3D Dice Roller
Roll realistic 3D dice with physics — d4, d6, d8, d10, d12, d20 for D&D, board games, and RPGs.
3D Product Mockup Generator
Upload your label or logo, map it onto a 3D box, rotate the view, and download a product mockup as PNG.
3D Text Generator
Create 3D text with custom fonts, colors, and extrusion depth. Rotate and download as PNG.
STL Viewer
View STL files in your browser with 3D rotation, zoom, and wireframe mode. No software needed.
STL to OBJ Converter
Convert STL files to OBJ format instantly in your browser. Free, private, no upload to server.
3D Printing Cost Calculator
Estimate the material and electricity cost of a 3D print based on filament type, weight, and print time.
3D Print Time Estimator
Estimate how long your 3D print will take based on layer height, print speed, and model dimensions.
What You Can Do with These 3D Tools
This section brings together practical 3D tools for makers, designers, engineers, and hobbyists who need quick answers without opening heavy desktop software. You can preview models, convert file types, create simple mockups, estimate print cost and print time, and experiment with interactive browser-based 3D effects directly from your laptop or phone.
If you work with 3D printing, the STL Viewer, STL to OBJ Converter, 3D Printing Cost Calculator, and 3D Print Time Estimator cover the common planning steps before you start a job. Designers can use the 3D Product Mockup Generator and 3D Text Generator for quick visual concepts, while the model viewer makes it easier to inspect geometry before sending assets to clients or teammates.
Private Browser-Based Workflow
These tools are built to be simple, fast, and private. In most cases your files and inputs stay in the browser, which is useful when you are reviewing client assets, testing print settings, or sharing quick links with collaborators. Instead of replacing Blender, Fusion, or other full 3D suites, this collection is meant to handle the smaller tasks that usually slow down a workflow.
