Issues are same as before but here is a new picture (although not quite as clear)
Profile is "Duet-PLA on glass,volcano,0.8 mm" .... doesn't make any sense whatsoever that it would not select the right ptofile. Makes the exported project useless.
I never had Cura report anything being non-watertight but am not exactly surprised. These non-watertight sections are likely only on the first layer as I had (and still have) problems with the interlinking protrusions of the model.
It's kinda hard to see but here is one interlink section:
What you don't see is that there is a gap that is 5 mm tall between the interlock and the main body of the model. The previous/lower model slides into that gap when stacking vertically. For some reason this fails very often in the print so I added some attaching wings that are 0.3 mm tall but they are kinda afterthoughts and likely would cause the error (although I have not seen it)
The first 5 mm of the attachment section is also very weak and breaks off easily. The print is rougher than the remaining section which is part of the main model. You can see a bit of that roughness if you magnify the picture. I suspect a pressure advance issue but it's very frustrating and a single print takes 5 hours ! -
It is possible that the issues with the profile and even the 'not watertight' are caused by us using different versions of Cura. I am using the 'Master' branch whereas you are using the 'official' Cura release.

I'll try with the master branch.

Still complains about being not water tight, and no profiles actually came across.

Looks like I am on my own on this Thanks for trying!
-
I'd still give it a run through netfabb. The fact that the errors are happening in between the two objects you suspect as being not watertight is all the more reason.
-
I installed a trial of Netfabb ..... my brain hurts .... and I haven't got a clue where to start
As far as the model is concerned - I printed a set of three and they came out just fine <shrug>Lastly but most important - I have abandoned the model because the 4 little interlocks on the sides of the model did not print well and keep breaking off. The damn thing is driving me insane!
Again, thanks for trying to help!

Oh you don't have to install the full netfabb, they have an online model repairing tool: https://service.netfabb.com/login.php upload the stl, it wraps a skin around the geometry and you download the stl again. Just need an autodesk login.

LOL .... yeah, that would be easier.

One last thought on these weird aberrations in case it helps others....
I have had deteriorating print quality that turned out to be under-extrusions caused by the BMG filament hob gear filling up with filament.
It is my belief that early indications of under-extrusions could be the cause. More specifically, the circumference of the hob gear seems to be right around the distance between aberrations and I am feeling that maybe there was a spot on the hob gear that was more plugged up then the rest possibly causing the periodic weirdness. I have no idea why it would only happen on a single wall and not the others (and not always the same wall).Anyway .... just thought I would post this.
