Based on my twisted gear vase, this is an ornament for your hanging pleasure. A 30mm round LED tealight fits snugly in the base (after you cut off the bottom) or you can just glue a hook on or whatever and hang unlit.
I entered this in ProtoParadigm's December Design Contest - Designer's Holiday : Winter Wonderland. Why not?


Print with zero infill and no bottom layers if you can get it to stick. I print with bottom layers on and just cut them off.
Make sure cooling is on or you won't end up with a pointy end. I sure didn't . Worked out though, they just have kind of a rough rounded tip.
If you print in nylon, dye them whatever color you want.
Insert a 30mm (approx) round LED tealight in base. With the 618 material, it's pliable enough to have the lights fit tightly but not hurt the print with the stress. I just push in far enough to leave the half of the light that you twist to turn it on. With ABS you might want to scale up a percent or two and glue the light in place.
Then drill a hole to attach a hook, or glue one on, or whatever you figure out works best for you.

partly to develop my 3d skills, and partly because i'd like to modify this to go over a "normal" led bulb (it will need a gluable base that's sized to fit and some thermal tweaking, such as vents), could you please post source files or notes?

I can post the .C4D file, but if you don't have Cinema 4D it won't be helpful. Let me know and I'll try to find/post the file this evening.

I made a few of these but the tea lights got do not fit. Can you tell me the exact tea light you designed this to fit? Mine were AGP Tek Cool White and are actually about 35mm in diameter.

Sorry for the delay in response. I used tea lights that I bought on Amazon. 30mm in diameter.

I had the same result. I don't think a tea light would work inside it anyway, as it would use up the air before long, unless you cut vent slits or something. It's a lovely design, but when it's done, there's no clear thing to do with it next.

See above. Not sure about your air-usage comment. We're talking LEDs here, not open flames.

That'd explain it. "Tea light" doesn't mean the same thing everywhere, apparently.

They're both tea lights. One is just a "flameless" tea light (aka LED tea light).

As usual amazing stuff. Question (though not on the object) how much venting do you use for nylon printing. Are we talking extractor fan?

Thanks! This is Taulman 618 filament (not just trimmer line or something similar) and it was formulated to print at 240-250C. As I understand it, nylon emits dangerous fumes when temps start pushing 300. I have a feeling that long-term, poorly ventilated exposure to melting plastic is probably bad for all of us that have printers "on our desks," but neither ABS nor 618 have measurable HCN release at regular print temperatures according to Taulman's tests.

So far, I'm really digging the 618. Prints great, looks amazing, and is functionally far superior to the alternatives.
