This customizer includes popular OpenSCAD library bundles that provide reusable components and advanced functions for your models.
Include library modules in your OpenSCAD code:
use <MCAD/boxes.scad>;
use <BOSL2/std.scad>;The customizer automatically detects which libraries your model uses and marks them as "required". You can also manually enable any library from the 📚 Libraries panel.
This example demonstrates MCAD library usage with mechanical components.
.zip containing multiple .scad files and dependenciesAdd interactive color pickers to your models by using the [color] annotation in your OpenSCAD parameters.
// Hex color with annotation
box_color = "FF6B35"; // [color]
// RGB hex format (with or without #)
primary_color = "#3498DB"; // [color]
secondary_color = "E74C3C"; // [color]When you add the // [color] annotation to a string parameter, the customizer:
Use your color parameter in OpenSCAD however you prefer (RGB arrays, named colors, or helper functions). The example below includes a working conversion helper.
This example shows how to use color parameters with a complete hex2rgb implementation.
You can also change the model’s display color without changing your OpenSCAD file:
Save and load your favorite parameter configurations to quickly switch between different variations of your model.
Use the preset dropdown menu to quickly switch between saved configurations. The parameters will update automatically.
Presets are stored per-file, so each model has its own set of saved configurations.
Export your customized models in multiple formats:
Upload ZIP files containing multiple OpenSCAD files. The customizer will:
include and use statementsA small ZIP project that demonstrates includes, modules, and the file tree.
By default, sliders and number inputs respect the limits defined in your OpenSCAD file. You can unlock parameter limits from the Advanced menu to enter custom values.
View the complete OpenSCAD source code, including all included files, from the Advanced menu. This helps verify that multi-file projects are loaded correctly.
Use Advanced → View Params JSON to copy or archive your current configuration (useful for clinics, classrooms, or troubleshooting).
Choose different quality levels for preview and exports:
The app is designed around a simple, repeatable workflow. A progress indicator at the top shows where you are.

Use Full Screen (Focus Mode) to maximize the preview area when presenting or when working on smaller screens.
The UI is built to support keyboard-only use, screen readers, voice control, and low-vision needs.
prefers-reduced-motionFull details, including tested screen reader/browser combinations.
This will reset all parameters to their original default values.
Any customizations you've made will be lost.
