Debby is always in motion. She is tinkering with the idea to find balance of the cane that would make moving it from side to side easier. She took some pipe insulation foam as a handle, a couple of padlocks to place weight at the back of the flashlight, some duck tape and she is off!
Right now she is just checking if not having to lift the nose heavy cane is actually offset by the back-end weight. Instinctively one would assume that he added weight would add stress to the wrist.
Well, Debby like to test assumptions and she feels that if you do not try, you really do not know. The picture below shows that the center of gravity of the regular blind stick is far ahead of the handle. That gives enormous pressure on the wrist to lift the stick.
The center of gravity of the back-end loaded blind cane is much closer to the handle as the regular one. What the effect in terms of comfort and ergonomics will be will result from further tests.
We are getting another step closer to the production ready version of the Marchena Cane. We printed Peter’s couplings and after some finishing we test fitted the couplings. The couplings fit well and after some strenght tests we managed to break one, so we will have to beef up the design a bit and tweak for even better fit and minimal play of the fibre glass rods.
For a first version from idea-in-Peters-head-to-design-to-print-file-to-print-across-the-globe-to-actual-fit it is quite an accomplishment.
Peter Hanely, our designer from across the pond outdid himself again with a very lean design for the connectors to make the Marchena Light-up Cane collapsable.
The previous design was a bit difficult to print with conventional 3D printers, it works very well for Selective Laser Sintering (SLS), but this Technology is not available in all corners of the Globe (get it?). We will use that design for special editions of the Marchena Cane.
This is very elegant and lean. I mean, does is get any prettier than thís?
This design is being printed now and after succesful test, will be available on our BYO page.
Peter Hanely from California designed the first version of the coupling for the project to make the Marchena Cane divisible.
This link fits onto itself, so the design is very easy to replicate for production. The design is also made in such a way that the current cane can be easily adapted. The VIB does not have to buy a new cane!
Naturally, the link will be tested by our discerning VIB test team (Oh dear!) and improved on the basis of their feedback.
The first step for enhancement of the Marchena Cane is there!
Peter has designed more beautiful things, you can admire his works of art on his shapeways site and download the 3D print files for your own project for a friend’s prize.
