The Step Twin D6 arrived!
Why the Step Twin?
Well, because it's the complimentary twin to my Stepped Die D6


I think this model is really pushing the boundaries in what can be acheived in stainless steel... the 1.2mm steps are only joined by 0.2mm strips and as can be seen the model is slightly skewed.

Also, in the same box...
http://www.shapeways.com/model/162900/]Twin rail mobius with ball pendant


The ball supplied with the model should have been 5mm diameter, it came in at about 4mm (by eye), so I grabbed a 6mm ball and retro-fitted it.

Definitely a better idea to add you own ball! Better action, fewer failed prints. A glass ball might look sharp too.

Own ball is the way forward... from now on I'm making all my 'can-have-a-ball' models so they can take a 6mm ball of whatever material... and maybe some speciality steel printed balls too

I came to the same conclusion about having balls in items. I still like trying to make it work fully printed, but for stuff that I sell directly to customers are working out better installing it myself.
These prints look very slick. Are they exactly the way they came from SW, or have you polished them?

Why don't you try to insert some of those " Reuleaux Triangles" instead of spheres? The faceted surfaces of these shapes would add some flash and even more mystery.

Interersting idea! But the problem might be that such objects wouldn't smoothly roll along a track of wires, although maybe this is the point. If you put them on a flat surface and put a plate on top of them, they always have the same width, just like spheres. But if you tried to roll them down a gutter they would have to bounce around because there would be two points of contact on the sides rather than top and bottom.
How do you get the ball in there if it is not made as part of the object? I assume you have to force it in there?

Yeah, i guess they would sort of roll along their edges not their surfaces? Might not work then. I'm sort of spatially challenged when it comes to visualizing forms in motion. That's why I prefer working with hand & hammers over computers.

Couldn't it work with a 4 barred system? the width and hieght would always be the same right? A 3 bar wouldn't because they don't stay consistent at 120 degrees.

Actually, I can't see a problem with using surfaces of constant width like Reuleaux triangles and such. The whole point of a sphere is that it can't escape because it always needs at least space "d" to slip through—and so does any surface of constanr width. The smoothness of rolling doesn't really enter into it, especially since that mostly relates to the height of the center of the object, and nothing is attached to the center.
Whatever; I think it should work.

A little update;
I bought in some 6mm chrome steel ball bearings and fitted 31 into my Twin rail mobius pendant. The balls really help accentuate the shape of the pendant.

If it helps, try these out. They are not technically surfaces of constant width, they're just intersections of spheres, but the difference between them and true Meissner bodies ought to be insignificant at this scale. There are 36 in this item.

One Year later...
The video Twin Rail mobius pendant with balls! is now getting about 9k views per day... and this is translating to 70-90 model page views per day, but no recent reported sales 
Does anyone have any pointers how I can (or what I might need to change) to increase the sales?
Cheers,
Paul

I don't know your background, so I don't know if you have a lot of experience selling jewelry or not.
I have been designing and selling jewelry for some time, and have found that people generally don't like buying a piece that requires any thing that isn't included. Even a lack of chain can, in many cases, kill sales. So since yours needs both the chain and the balls, my guess is that that is the reason for a lack of sales.
Another possibility is that people don't like to wait. So it's possible when they go to order it and realize that it could be a month before they get it, they give up.
Sadly, I don't have an easy solution for you since, obviously you can't include that stuff via shapeways. You could however get a bunch made, buy a bunch of chains, and bearings, put them together along with a gift box, and then sell them yourself.
You could put a link to your own site that sells them on your youtube page. Of course then you need to lay out a bunch of money, and keep stock as well as mail them out yourself. So, it is a lot more work.

Novaking has good points there.
It's looks a bit too much DIY/experimental now.
And if you don't already have, I would put up a pack of matching (S&F) balls in your shop.
If you stack them closely with enough space and a mesh cube around it, it would make it easy for handling and shipping to make sure none go missing.
Perhaps also offer quarter/half-packs so people can mix and match colors.
The (short) description on your model page is a bit dry:
| Quote: |
A pendant incoporating a double mobius style loop to take a 6mm ball.
A 6mm steel (or other) ball bearing can be retrofitted, as seen in the default photo.
The updated model has a 4mm loop for attaching to a necklace.
|
And on youtube you also have an elaborate description where the link is not visible in the shortened version.
As far as I can tell from my experience, long and elaborate descriptions are not very useful in promotion and sales.
I recommend adding only the following line to the youtube video description:
"Info and purchasing: http://shpws.me/D6g"
And remix your current descriptions to a short and snappy one.
Perhaps followed by the more in depth description below the more button and a separate <h1> heading or similar.
I think the first four lines of text are crucial to making a sale or stir interest.
A twin-rail mobius pendant<br>
An endless and mind-warping cage for a train of 6 mm ball-bearings. Or better yet, or get the colored </link>supermarbles</link><br>
<h1>
What why how.
Etc
And then read it back as if you are completely new or find someone who is 
Do the sentences read swiftly?
Is it to the point?
Does it say what you mean to say?
Cheers!

novaking & virtox, thank you for the tips 
Carrying stock is something I am trying to steer away from, but it is looking like I must go that way to succeed!
@virtox, the long & elaborate youtube description is for matching the keywords for advertising revenue purposes - I have added the short "Info and purchasing: http://shpws.me/D6g" so that it is the only thing visable before clicking more info

Personally I'd like to see the design shown packed full of the stainless steel balls, and one brightly colored glass ball, like orange. Then you'd have a good reference for movement & rotation of the balls.

Cheers Jeff, funnily enough a YouTube member commented the same but with a yellow ball earlier today. I wear this pendant on a daily basis with a single blue ball (+30 normal steel) and I do get comments about how effective it is.

@virtox @novaking Sounds like good advice.
One thing that always catches my eye whenever I'm browsing is products which are presented with some sort of story.
Doesn't have to be elaborate, but something that paints of picture of the product in the context of everyday life. For example, Paul, what inspired you to make this particular design? You say you wear it often. What have people's reactions to it been?

Hi Ana,
The inspiration for twin rail came from TerraCotta's One ring to rule the ball - Twin Rail is a take on that but with 6 3 wires that have loads of balls.
When I'm wearing the pendant, people's reaction vary from wtf to wow, where can I get one... but sadly as yet no one has walked up to me and said I've seen that on the internet as happened with one of my LEGO creations at an exhibition a few years ago.
Paul
[edit] call it what you want... maybe cynical, but, what kind of story need to be attached to a product? Surely, it is what it is, how do stories affect sales?

I don't think "I was inspired by another artist's work" makes for a very meaningful story. So, I wouldn't go with that one.

I guess TerraCotta's description (from your link above) is about as good as they get - perhaps you can take inspiration from that as well. There's no fibbing there, just a little story and a great description of the product. Do you think it may be worth the $$ to hire a copywriter to put a description together for you?

After some sleep and sunshine this morning, I think I cracked it 
| Quote: | Inspired by the well known mobius strip (discovered by August Ferdinand Möbius in 1858), an interest in the unusual, and 3D modelling, I created the Twin Rail mobius pendant.
A half shell and 3 rails form a bearing-like structure to encapsulate a train of 6mm balls in a mind-warping cage with a twisting, fascinating movement bringing to life the only pendent of its kind in the world.
Includes a 4mm loop for attaching to a necklace or leather cord.
See the photographs with retro-fitted 31 6mm chrome steel ball bearings... in the bottom photo, the balls have been heated until they 'blue'... check out the video to see how they move by clicking on the little icon below the camera above.

Picasso once said something like:
"Mediocre artists borrow, great artists steal"
Meaning, it is a delusion to think that anything a person does is completely without influence or inspiration. How a person interprets, employs and expresses these messages will always separate the wheat from the chaff.

Well, a couple of more month further on and I've lost count of the amount of sales for the Twin Rail mobius, but the video Twin Rail Mobius Pendant - with Balls! 3D printed metal @shapeways is fast approaching 1 million views with still a sustained 10k+ views per day.
I've made another video, Twin Rail Mobius Pendant - with Balls! - Answers., that answers some questions from the comments left on the first video. The good news is that 1/4 inch balls also fit!
As yet, I've not added a model for the balls, but an experimental 'ball dispenser' will be in my next order along with another mind bending mobius design 
Cheers,
Paul
