are you able to help me make this kind of "square notch tooth" pattern in 3ds? I want to make nose cones and body tube wraps for my rockets using this "square notch" type pattern. but I can't figure our what shape would result in this in 3ds max ?

I actually modeled this in C4D, where there's a "Cog" pattern built in as a preset configurable path. I would think you could create a vector path like that in Inkscape or Illustrator and import the vector into 3DS to loft it, but IDK.

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.
