Aperture Science luggage tag, for CSE 340

science_luggage_tag.scad

// rotate, translate, mirror (solid)
// union,
// difference (subtract shapes), 
// hull (fills bounding box as tight as shape input)
// linear extrusion is a thing


// Inner triangle shape
// polygon(points=[[0, 0], [100, 0], [0, 100], 
//			   [15, 15], [65, 16], [15, 65]], 
//		paths=[[0, 1, 2], [3, 4, 5]]);


// also can import a dxf file
// extrudding text works too!

// CHEAT SHEET:
// % shows something tarnsparently
// $fn sets resolution (lower for high perf)
// module name() {}    // functon!
// Can use for loops
// Can use other people's libraries
