Old design method: draft board; new technology: 3D printed parts

[Roadjunkie1]

Here is my original design done on my draft board, on......what's that stuff called?............oh, yeah: draft paper done with T-square, compass, triangles and lead pencils!

3D printed part(s) from that design, printed by a friend of mine, and what they are being used for. Amazing technology! The parts are light weight but amazingly sturdy. I want to saw one in half just to see the interior structure, but it takes nearly a day to print one! More to follow on the O2 setup coming.........watch this space....!

My career began in the days of drafted blueprints. I can say with certainty, since CAD's proliferation, both the quality and speed of engineering and design have fallen.
