In a world full of 3D tech I have some older Red/Cyan Anaglyph cardboard glasses that are slowly falling apart. The filters are good though so I have designed these as a replacement for them. I am no fashion guru so the design is a bit geek-chic.

The arms are currently fixed so no adjustment once they are glued into place.

I use these to check how my model will look in NetFabb's 3d view.

All the randomness of a Russian Roulette game, without the drama.

I was thinking that putting numbers on dice when we can put pretty much anything we want was... a little square. Since a cube is simple to design, I figure I'd start with a d6 die. Die... hey, Russian Roulette!

Tasteless, and easy to express with simple emoticons, so no need to draw or anything.

Univers Revolved is an art project from Ji Lee, pleaseenjoy.com . It takes the roman alphabet and remakes it into a set of 3D, solid objects with axial symmetry.

Words can then become objects, letters stacked, attached, etc... Check out the possibilities at the universrevolved.com website.

When I saw this online a week ago, I knew I had to get it onto Thingiverse, so I reached out to Ji Lee, who was kind enough to grant permission, and express some interest in what we do here. We're hoping to print out a few of these and go see him with a MakerBot soon.

With permission from the artist... Thanks, Ji Lee!

There are puns I do not have the strength to resist...

The only tricky bit was designing the system to attach this proud token of your status as a veteran Maker. I think it will print without supports, and I think it will work as intended.

TMR posited it might take half an hour to make a d20 in Sketchup... it took 35-40 minutes, including figuring out a good process.

For the record, I used TopMod to generate the original twenty-face regular solid (it's an icosahedron, I believe, but my memory may be faulty), and I also cleaned up in Meshlab (couple clicks just to make sure the mesh was ok).

It Skeined great, at least for the jumbo size dice.

Here's what I meant by a cuff, a much wider bracelet so the text can be supersized.

I also ran the mesh thru Meshlab, this time, and used the 'close holes' command, which fixed all the little issues with this object in one click. Very handy!

Judging from the gcode Skeinforge put out, the resolution is more than enough for letters that big.

Inspired by Zach's bracelet V1, and some other things he showed me at NYCR yesterday...

I think the bracelet may be too thin to print with enough resolution for the text to look good, or even be readable. Might need to make something more like a cuff, with a single word, perhaps?

EDIT: The combined mesh/toolpath detail view of the first word on the bracelet actually looks better than I expected. It won't look perfect, but it might be quite readable... and clearly, slightly larger text should look great!

Skeinforge wasn\'t happy with the last version of the Hexagonal Box, and after some discussion on the Thingiverse Google Group (recommended reading, by the way), Zach pointed out that non-manifold vertices were a possible culprit.

Well, turns out he was right! I went back to Sketchup, eliminated all the points in the model where two pieces of the model touched along a single edge, ran it thru MeshLab to check for mesh defects and export to STL, scaled the STL in Blender, and then ran SkeinForge on the STL file... getting a beautiful toolpath.

Thanks to everyone on the Group for the suggestions/tips/tricks!

This variant of the Hexagonal Column does away with the FlatRoll concept and goes for interlocking tabs instead. No need for a flexible substrate, six of these segments should lock together to form a box.

The 45 degree overhang rule is met, and the individual parts are much bigger (no need to share the printing volume with the other five) with finer details, so this should print out fine.

EDIT: Added an anaglyph picture, bring out your red/blue glasses!

Took some finicky fiddling but finally got a hand-drawn Klein bottle with all the normals going the right way, and was able to import it into TopMod and play with it.

The 'simplest' variant has not been subdivided in any way... it's a good starting point if you want to adjust the overall shape.

The 'skin' variant has been subdivided using the Doo Sabin remeshing option in TopMod, giving it a rounded, smooth look. It might make a very infuriating teapot, I suppose.

The 'bone' variant is the same as the 'skin', but with more visibility inside.

To get a good idea of what is going on inside, some of the pictures of the wireframe views of these Things are your best bet.

So this answers the question: Yes, we can make a Klein bottle.

EDIT: Added an anaglyph image, since this is a confusing shape. Getcher red'n'blue glasses, step right up!
