The last time I put my store in vacation mode it crushed my search results for a year. They say it won't but everyone seems to have the same experience i had. Now I just take orders and send a message to the customer.
I remember hearing thicker layers like 0.8mm gives you stronger prints. So basically dividing the model up less makes it stronger, when the model is so big you divided it up more then a smaller model, so diving it up more made it less strong. Basically bigger models need thicker nozzels for the same strength, or you can redesign them.
Totally makes sense why they crack. A really small model the slight flexibility of the filament offers sufficient compliance to accommodate the relatively small movement of the ball being pushed into the joint without reaching the limits of the material. One side of the joint is under tension, the other under compression, these forces are much higher the bigger the model, as the forces scale up so do the stresses and strains, which then overcome the layer adhesion and the strength of the filament too. You need to redesign the joints. You could split the joints to aid assembly, but you will also need to do something to meet the other requirement which is to have sufficient friction in the joint to withstand the weight of the model but still be poseable.
Its the nozzle size, when you make the model bigger you divided it more in effect decresasing the nozzel size, we all know increaseing nozzel size makes prints stronger, so decreasing it makes it weaker. You could get away with no redesign if you scaled up the nozzle size with the model.
The parts don't scale up because in the small printed model, that C cup shape, the material is expected to flex a few thousands of a inch. You are also scaling up the expected 'flex' or tolerances to something not possible in the rigid larger part.
I don't think your going to be able to get away with scaling it up without doing a good bit of work to make the joints function like they do when it's smaller. If you do want to spend the time to do the work, I would pitch splitting the joints and putting screws in place to clamp them together. That lets you be able to take it back apart whenever it's needed without destroying it.
Your walls are too thin at that scale. Think about it. When they are smaller the walls seem thicker when you scale it up you need the scale the wall thickness too
The camera is super clear and stable.

You should try adding a few more walls when scaling up

you perhaps should print the joints in flex 90A to have a little flexibility.

Have you tried heating the joints on the large dummy 13?
Lol, some light damage. Dead blow hammer?
I got out the hammer drill
I miss the daily Videos i love watching the content you make and love watching it every day LIKE THIS COMMENT IF YOU AGREE
Why cant you simply put the part in Tinkercad and use a negative cylinder to make the joint a fraction bigger ?
could you not make the part you are clipping onto a oval where you slip the part on the smaller part and then turn it to the fit
