Can anybody produce a clean "for dummies" example of HTML for using STLLoader.js to display ASCII (not binary) .stl object files in a web page? Result should let users manipulate object in current HTML5 browsers and with no fancy visuals beyond a grayscale object surface and background.
STLLoader.js might need the help of three.js or three.min.js but I wouldn't know. STLLoader.js contains below usage example but did not include an HTML wrapper.
Usage example inside STLLoader.js
/**
* Usage:
* var loader = new THREE.STLLoader();
* loader.addEventListener( 'load', function ( event ) {
*
* var geometry = event.content;
* scene.add( new THREE.Mesh( geometry ) );
*
* } );
* loader.load( './models/stl/slotted_disk.stl' );

Click inside the file drop area to upload STL file or drag & drop STL file. Click on Convert button. Your STL files will be uploaded and converted to HTML result format. Download link of result files will be available instantly after conversion.
STL is a file format commonly used for 3D printing and computer-aided design (CAD). The name STL is an acronym that stands for stereolithography — a popular 3D printing technology. You might also hear it referred to as Standard Triangle Language or Standard Tessellation Language.
The three.js examples are a good source:
