## What it is
A fast, lightweight thumbnail generator for 3D model files (STL, OBJ, 3MF) written in Rust using OpenGL. It integrates with file managers on Linux and Windows to show previews of model files and can also be used from the command line.

## Use cases
- generate thumbnails for STL files
- show 3D model previews in my file manager
- render STL files to PNG images from the command line
- preview 3D printing models before printing
- batch generate images of 3MF and OBJ models
- see what an STL looks like without opening a CAD program

## When to choose
- you need fast, lightweight STL/OBJ/3MF previews on Linux or Windows
- you want file manager thumbnail integration for 3D printing models
- you need a CLI tool to render 3D models to images
- you want a Rust library for rendering STL files

## When to avoid
- you need full 3D viewing or editing capabilities rather than thumbnails
- you are on macOS, which is not supported
- you need to render formats beyond STL, OBJ, and 3MF
- you need a GUI application for inspecting models

## Facets
- artifact type: cli-tool
- maturity: active
