Sorry for the lack of updates, this has been slow going now that I have a full-time job rather than being purely self-employed, and all my free-time has been dedicated to raptor claws, BUT i've been working at this while waiting for claw castings and paint to draw, and during lunch break at work, and so now I have finally assembled all the pieces (sans the vacuum formed parts).
I designed and printed an inner chassis, and while it broke in two due to some print-errors, after some hot-glue action I was still able to assemble the petals onto it.

and here it is next to the original:

The petals aren't perfect, one of the sets broke in two and I don't think I did a great job glueing it back together, so some of the petals sort of stick out farther than they should as a combination of a bad glue-job, and because the water-washable resin sort of warped in the cleaning/curing process. The chassis helped straighten most of them out, but some resisted. It's good enough for a prototype and to test out some painting techniques.

I'll have to save up a bit more funds before I test out some electronic bits, it's not terribly expensive but until I work a few more weeks my wallets not terribly stable.

I'll post an update either once I test some more vacuum forming or after I install some electronics— the later might be a while, so until then!


PS: Does anyone have a for-sure measurement for the original prop? I feel like this might be a bit big, but the circumference is juuuuust over 10 inches, which seems about right??

I just rewatched NWH on bluray and it made me wonder how your replica is coming along.
Unfortunately it hasn't gotten much farther. I have all the inner components, but I still have to teach myself how to properly wire these electronics/the Arduino sound board and lights. Plus the programing. Its tricky trying to balance this stuff now that I no longer set my own hours

I DID put together a couple sound files based on the two scenes of the beeping countdown we get in 3, plus some extra from-scratch noises based on what we get from both 3 and 1. Still playing around with the foley-work of it all.
Maybe I'll have both versions on the soundboard?
Will be working on a NWH version of it too (it's more of a hum/buzz)

After a Pumpkin Bomb showed up on the Prop Store, I'm trying to tackle this myself. I started with trying to figure out the hardware sizes and going from there. It's a small detail, but I believe the hardware might be M1.6 instead of M2. The size and profile of the head seems to match a little better. A standard 5mm LED was used for size reference. This all jives with your 8cm measurement that you have for the diameter.

Where was this all when I modeling the first time around?!

Thanks a bunch for posting this here— they are fascinating! Before, the only actual look we got onto the 2002 prop (there was a mislabeled one from 2007) was the stunt casts, which I have and have been taking measurements from. Problem is, the stunt cast doesn't have the right size for the LEDs, and it has no screws, and it's missing details like what the bottom actually looked like!

Like what's great about this is that it looks like the bottom copper disk (where the button is on top) is SEPARATE from the bottom ring, and likely where one could access the batteries/inner electronics. I'm debating if I should leave the bottom smooth now or add those screws. You can also see that the screws were hand drilled, as they're not dead center of each petal. Fascinating stuff.

I was trying to make it so that the screws on the petals were actually functional and you could remove them to access the inside, but now I'm debating adding these screws on the bottom... Like I could, but also I know from the 3D model in certain scenes they aren't supposed to be there in the context of the movie, but adding those bolts would make it more accurate to the prop itself. I'm gonna do it!

Is the model of the screw on the right an M2? I will say, I've learned in recent months that the M measurement doesn't necessarily effect the head measurement (since its the bolt diameter.) For example, the M2s I use have a head diameter of 2.5mm, and there are some M2s in my kit that have 3mm diameters.

I do think the 3mm heads of the M1.6 screws you linked are even a biiiit too wide, but it's hard to say. As you measure a picture of a curved surface it can be tricky to get an accurate measurement of parts further along the curve compared to a measurement on a different part of the surface. Using the knurling width as a closer point of reference (and width of the top of the petal based on the 5mm LED and reaffirmed by the prop I have in hand) I'd say the diameter of the head is close to 2.5 mm (ranging between 2.5-2.75.) So the M size ultimately won't matter too much as long as you get the right head diameter (and make sure you get an allen head, not a torx.)

I look forward to seeing what you make! The more pumpkin bombs the merrier!

A quick update where I'm at in my build:
This has been on a bit of a hiatus, as I knew a while ago I needed to scale up the holes from the LED (it's much too small for a 5mm!) I bought some 3mm for this prototype, but I might also just drill the holes to be larger.

"But why don't you just print another with the right hole size?"
Excellent question. Reason number 2 for my hiatus is that my 3D printer needs a new screen, and I haven't had the time to research and replace it. Honestly, if I decide to make more of these in greater quantities, I might just invest in a new/larger printer.

And thanks to the new photos, I also have some minor tweaks to make to the bottom and top plate.
Speaking of which, can anyone identify this odd looking screw/bolt/whatever this is? Looks like some kind of thumb screw??

Reason number 3 for the hiatus, is I had no idea how to wire/program this thing. After installing and re-installing components for a neopixel lightsaber, I'm feeling much more confident in my soldering skills, but I still need to learn the programming part, which I'm hoping to tackle this week.

Meanwhile, this past week I painted the base coat on the actual parts!

Appreciate the stealth paint on these as I wait for some new airbrush replacement parts to come in (everything's breaking!)

You've got the spacing of the holes from the outside of the ring right on, but they do cut into the black ring a tiny bit.

The auction description mentioned charging ports, so I've been trying to find some that match. I haven't been able to find any that have the slots that go across the entire port.

I noticed! And I'd actually say the spacing for the holes are also a bit off on mine. Needs to be closer to the edge.

So in the description of the auction it describes a charging cord, it unfortunately doesn't mention anything about if one of those are a charging port (though I wish it did.) My best bet is that bottom disk comes off and has a charging port on the inside.

But great minds think alike, that was my first thought too! And I was thinking about juts modeling the parts to look like a threaded insert and then making it into a hidden charging port, but I think for now I'll just keep things simple and have it be under the disk.

Honestly the bottom bolts look like some kind of socket cap bolt head.
