Summary

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 styles. I was origionally thinking that two mid segments would be appropriate for a "Symbol Cane", but after printing I think maybe three would be better. For a "Guide Cane" at least four or five mid segments would be required, and for a "Long Cane" six or more might be appropriate. The current design should probably not be used as a long cane as the segments just use friction to hold together and the join might not be strong enough. I plan to "lock" the pieces together in a future version. Any advise on locking mechanisms that are "blind friendly" would be appreciated.

I'm also planning to smooth out the mid section in the next iteration.

This is also my entry for the "Print to improve life quality"(http://forums.reprap.org/read.php?282,220067) competition. Wish me luck.

Hello! I actually came here because I lost my cane the day before hurricane Irma here in Florida, US. I have an idea for the locking mechanism that should more then suffice without having to worry about finding out the spring properties of PLA, ABS, etc. What I was thinking, is rather a push, twist, pull, and twist locking mechanism. By this I sorta like the gift maze box found here: https://www.thingiverse.com/thing:818193
Of course, nothing that intricate. The way it works is that it has a little half-sphere sticking out of the piece to be inserted, and there is a ridge that received is. Once it goes in all the way to the bottom in a straight line, you can twist it right, pull up slightly, and pull to the left to lock it in place!

Edit: I also forgot to reply. The radius of most canes (at least here in the U.S.) is between 5 to 7 mm. One of the most important things that is missing the a flat side on the handle where your finger is supposed to rest in a straight line. I wish I could point you to a schematic or a picture of this, but since I don't have a cane with me, I cannot. :(

Maze gift box (hard to open)

Thanks for the feedback... I didn't realize about the flat spot, but it makes a lot of sense.

I haven't been working on this recently (broke my printer and haven't had time to fix) but will incorporate your suggestions when I get back to it.

The better locking mechanism I was exploring was a half sphere and socket design, but I was trying to put it on a "U shaped tab" that could flex in and out a little... The "maze" concept would have less wear and tear by removing the need for flexing :D

Hi there Puzzleduck. My name is Damon, I'm a journalist at the BBC in London. I'd like to get in touch with you. If you're on Twitter, you can find me as damonrose - I'd like to mention your cane in an article and get permission to use an image of it. Get back.

Hey Damon... great to hear and just in time as I'm about to release another version (hopefully an improvement :D). I'm technically on twitter but I only check it when it emails me, so you can cut the middle man and contact me at [email protected] Cheers.

my tent pipe structure have this sort of pushbutton made with a U shape spring with one button on a side.
the U is forced into the inner pipe with the button peeping outside a hole.
the head of the button is long enough to interlock with a hole in the outer pipe

in italian "cane" is the dog and the yellow mark it should be internationally understood as "beware at this anti-social dog" or something similar.... in a few words, if you have a dog stay away from mine ;)

dogs apart, I figure your cane popping out while the blind is crossing the street...

it could be useful having a kind of interlocking with pushbutton release

sorry for my poor english...

hey, thanks... nice little bit of cane trivia :D

I was thinking of a push button style release, kind of like some tents or umbrellas have... just need to learn how to do it hahaha.
