Saw this on http://boingboing.net/2012/02/27/clever-assemble-yourself-toys.html, but thought the old version was much prettier (link: http://www.artifacturestudios.com/archives/30/ - simpler, more elegant!).

So I fired Illustrator up, found the original blueprints, and a couple of hours later, hey presto: Eiffel Tower!

The first version is scaled to fit 2 pieces of A4 paper so it is not yet as elegant as intended, but if you download the original (EiffelBlueprintBeforeOutline.eps) you can scale it to fit your needs before outlining it.

The second version is scaled to A3, and will end up being ~38cm's high...

Lasercut & assemble. Done.
