Recently got my attention drawn to an open source CAD app: OpenSCAD, it's quite different from the usual CAD suites by being strictly script based, apart from the obvious drawbacks it boosts strengths only seen in the high $$$ apps...making it easy to design complex parametric parts with only a few lines of code...best of all, it's free 
So after playing with it a bit I decided to attempt designing a Ti base with known parameters...and here's the result, it is relatively easy to get things done once you get the concept of it, the documentation is good and there are lots of tutorials on the net as well:
Attaching the code here:
Copy/paste it into OpenSCAD, hit F5... and enjoy... To save it into an STL , click on the STL button as shown:
The code is somewhat documented, but if you got any questions about it, don't hesitate to ask
