Description
STL model previews can use this Tumbler thumbnailer to generate custom thumbnails for 3D model files. It helps Thunar and other Tumbler-aware file managers show visual hints for printable or CAD-like STL files.
Use it as a thumbnailer plugin, not as a standalone app. It invokes OpenSCAD-related preview work on user files, so large or untrusted models can affect performance.
