Threadless Ball Screw generator (by Tim Chandler & "messed up" by me)

I rewrote a script written by Tim Chandler to suit my requirements. Next, I need to test it on a printer but the process of modifying it for OpenScad was educational! http://www.thingiverse.com/apps/customizer/run?thing_id=124706&code=3ac9ddfc7fbd1cd6feecb55e21ff29da http://www.thingiverse.com/thing:124706 I recently updated the design, addressing a problem where engraving details would sometimes vanish when dimensions changed. This issue was fixed by relocating and adjusting the engraving position. 2015-Jan-05: I revised errors and introduced new vectors that establish bearing measurements, plus created tables to determine nut sizes accurately. 2015-Jan-08: The base dimension has been increased, the code was reviewed and several more details corrected. I printed and tested two items with pitches of 1mm and 2mm. The results were perfectly successful!!!
