How do you write STL? struct.pack( b"<ffffffffffffH", normal[0], normal[1], normal[2],
x1, y1, z1, x2, y2, z2, x3, y3, z3, 0, )
Should I have used NumPy? Yes. Did I use NumPy?
Err, no.

4. The Future
More US National Parks I do each one as I
visit it. There are… 59.
Easier Milling 8 hours per piece. Really.
Better STL optimisation Millions of polygons isn't great.
Personal LiDAR Thanks, autonomous vehicles!
