Cad drawing needed

Anyone know where I can source a cad drawing of the top triple tree for a 5th gen?  I'd like to experiment with some 3-d plotting ;0)

Just use the known offset, fork tube diameter, and fork spacing, and shape away.

Thx yoshi, I am actually playing with an "overlay" for the factory top triple clamp.  I was hoping to cut down on trial and error by having a good base to start from.  I've considered buying an eBay triple, but was hoping to avoid the cost and time.  This may be my best option, so thanks!

What's your end goal?

Custom 1/2" overlay with engraving.  Top secret, patent pending ;)

0.5" is pretty thick for an overlay. Or is it something else.
