Nutribullet Thread Form Identification 2

[Coutts]

What is the thread form on the 32oz Nutribullet plastic blender cup?

Example...

https://www.amazon.co.uk/NUTRIBULLET-Colossal-EXCLUSIVE-Nutri-Flow/dp/B01HHA11YY

I love my Optimum 9400 blender, it will blend almost anything. The only thing that annoys me is the lack of cup options. The cups on the Nutribullet would be perfect but im not having multiple blenders on my counter.

So I sat down the other day & started to model a special lid for the Nutribullet cups; one that fits the Optimum blender and uses their blade assembly but allows for Nutribullet cups to screws on.

Its a pretty straightforward design but when it came to the plastic thread form on the cup I got nowhere. I have zero experience with threads of that type and extracting details from Nutribullet failed miserably.

It could be a custom thread but im hoping its a standard form which I can reference?

If its a custom thread can a turner copy a thread form and flip it to make the mate?

Thanks in advance for any assistance.

Will a mason canning jar screw onto the blender?

Pull out the measuring tools and Machinery's Handbook and treat it as any other reverse engineering project, then hand it off to the turner/machinist/lathe operator of your choice. Most anybody that can operate an engine lathe should be able to reproduce most any thread with reasonable accuracy.

Would a 3D printed part work? You will still need the details of the thread, but you eliminate the machinist . . .

Thanks folks for the comments...

I don't have any jars big enough but thats a good point, ill try and find a spec for mason jar lids threads to the google searches.

Im most likely going to end up going down that route. TBH that was the reason for posting, I was hoping someone knew the thread off the top of their head and could tell me the correct drawing annotation but hey ho nothings ever easy.

3D printing isnt really an option (not the ones that would cost less than machining) due to the jarring force, maybe on a lesser blender.

You do know that some printers, even some of the "home hobbyist" level units, will print with the addition of carbon fiber. They are printing tooling for production use with 3D printers these days.

Are any home hobbyist versions capable of printing with food-safe materials, and with a level of smoothness/non-porosity that would keep it from (worst case) harboring trapped food→bacteria, or at least being a PITA to clean?

Absolutely. Not a problem.

And easily strong enough for a NutriBullet base. There are many food grade filaments out there and they don't even have a price premium. Medical grade filaments too.

Its for an optimum 9400 2.4kW blender. I don't have access to a 3D printer which would mean Id need to outsource it and hope it doesn't explode.

I do however have access to a mate of a mate with a lathe and a 3 axis mill with lots of offcuts and who'll make it for beer.

Either way still need the thread form to make it.

Understood. Just that with a 3D printer you could make some measurements add in a few estimates spin one and try it for thread mating quality. You could do that with standard old PLA. If you have problems tweak until you're happy. Then you know what to machine. Someone around your area must have a printer. There are also lots and LOTS of online printers.

3D scan the threads?

You could use a transfer router. No need to measure anything after ensuring enough material is present.

Now theres an idea, I have all the bits needed to make a kinect v2 3D scanner, probably need to coat the cup but thats not a problem.

Sounds like a plan,

 

[itsmoked]

Do tell how that goes! Thinking about doing that for a few things here.

Don't forget that Autodesk has a product/service where you take a bunch of pictures of something at regular angles and upload them all and after a couple of hours they return an excellent digital rendition.

Here's a vid on it:YouTube on Photometry

I think that was supposed to be photogrammetry.

TTFN (ta ta for now)
I can do absolutely anything. I'm an expert!
