With a simple shortcode you can enable and embed a WebGL viewer to show 3d stl files.
In the current version:
<ul>
<li>STL files have to be uploaded to /wp-content/uploads</li>
<li>The viewer can’t be used more than one time per page. This might be a feature because the viewer needs a lot of resources.</li>
</ul>
A complete description of the plugin can be found on <a href="https://www.db4cl.com/projects/stlviewer-1-0-for-wordpress/" rel="nofollow ugc">my blog</a>.
