Bathsheba @MichaelMueller Psst! This is featured in the "last minute gift guide", and the Presta link is broken. Feel free to delete this comment.

Bathsheba @nocturne The brass and silver pieces here are made by casting wax prints into metal, and the size limit for those is 89 × 89 × 100 mm. So I can turn on this smaller size in those materials, but the larger size on my site could be printed here only in the steel or plastic materials. I can certainly turn on either of those options if you like; just let me know.

Inscribed Klein Bottle Opener
Bathsheba @johnjdoe1238 Yes, it should be possible to engrave it. The metal is funny stuff, part steel part bronze, but it's solid. I use an engraver to write my signature on the bigger pieces that I sell on my own site, so I know it can be done!
Bathsheba @johnjdoe1238 Hi, then you might need to write to customer service,, to cancel the order? I can't see or affect orders other than my personal ones: I'm not really in the loop at all with yours. When you're typing in the inscription, it should show you the live 3D model, with the text on it, in the picture at left. So while I can't check whether that's working, if it is you should see a drawing of a Klein bottle with that inscription. If you're not seeing that, it hasn't worked. Again sorry for the confusion. Hope this helps!
Bathsheba @johnjdoe1238 Hi, sadly I can't affect an order that is in progress. You can probably still cancel it and start over? To get these inscribed, you type in the message that you want in the "Custom Text" box at right. Then it should show you a preview. (But unfortunately it doesn't do punctuation.) Sorry for the confusion!

Bathsheba @John_Dorce A very valid decision. :-)
Bathsheba @John_Dorce I put it here:
Bathsheba @John_Dorce How big do you want?

Bathsheba @moroplogo@moroplogo The models you link are not mine. This design is often plagiarized, and you have found some examples of that.

Metatrino Pendant
Bathsheba @lilili Sure, I've turned it on. I usually leave it off because the name is misleading -- the material is not a stainless steel, it's the same steel/bronze metal as the other steels -- and I think the other steel finishes are prettier. But if it's your favorite, go for it!
Bathsheba @adam_kope I'm not sure it'll print, but I see the printability wizard thinks it passes the guidelines so what the heck, I'll turn the steel materials on.

Bathsheba @payprplayn Mathematica, Surface Evolver, Rhinoceros. It was a long time ago though, and you might be able to do the whole thing in Rhino now: people do very fancy math in Grasshopper and other plugins. (I still use Surface Evolver though -- the docs aren't easy reading, but if you're serious about minimal surfaces it's the tool for the job.)

Bathsheba How do the parts stick together, do you have to glue them?

Bathsheba @nocturne At this size no. I did try; I think the problem is that the green part collapses. If a smaller one might be interesting, I can set that up. Let me know?

Double Zarf
Bathsheba @nocturne I agree -- metal printing technology is in a state that people will later see as endearingly primitive, in just the way we now think 8-bit graphics are cute. There is a touch of sabi about that flawed surface, which is unexpected in an object billed as "from the future". PS Thanks for the photo!

Klein Bottle Opener
Bathsheba @PhilHibbs @geeklodge Thanks for the note geeklodge! Word. I must beg to differ Phil: the coolest thing about a Klein bottle is that everything is already inside it. You're right that the circle of self-intersection is an artifact caused by embedding the bottle in 3 dimensions, but it's not a defect. Whereas cutting a hole would change the topological genus -- I'd have to retitle it "Möbius Shorts"!
Bathsheba @PhilHibbs It is closed. Otherwise there would be a hole in the bottle, and I would not like to ship defective ones.
