White Cane

This is very much a work in progress, and is not simple to print yet.

Please forgive my yellow "White" cane :D I just couldn't resist (and I'm running out of white).

This is intended to be a "White cane" (http://en.wikipedia.org/wiki/White_cane) for the blind or visually impaired... Warning I have no experience designing disability assistance devices nor do I have any experience with the blind or visually impaired, but I am open to feedback and willing to learn.

I think the diamiter is a bit too wide and I'm planning to thin down the next version (I keep thinking in diamiter, but OpenSCAD thinks in radius). Again, I'm not sure how wide a normal white cane is so feedback from people who might know better would be great.

You will need to print at least one handle and one end piece (warning: the end piece ball will require at least a raft... mine still moved... improvements to this are already planned)

The modular design is intended to accomidate a variety of users and cane
