+1. Create the model as a **file note** (title ends in `.step` / `.stp` / `.stl`),

+3. On the share, the link to a model file note is replaced by the inline viewer.

+## Trilium app widget (independent of the share)
+
+The same viewer is also available **inside Trilium itself** (independent of the blog):

+Wire it by giving the JSX note the label `#widget=3dModelViewer` and reload the app.
