Multiple joined components in one STL generate shell walls between components

· Multiple joined components in one STL generate shell walls between components
It's not the slicer really. If you don't combine the parts, there will be a surface between the two objects. Since STL doesn't actually define what is inside or outside (it only defines surfaces) you get weird results like that.
I've taken a screenshot of the uncombined version of the file to show you what the issue is:
As you can see, there is a small gab between the two objects. This gap is caused by the tessalation (eg; It needs to create flat surfaces, so a round surface is approximated by multiple flat ones). This process will pretty much always introduce inaccuracies, which can lead to gaps like this.
The result that you see is basicly your slicer doing exactly what you ask it to do; There are two components and they are printed as two components.

Thanks @nallath for your advice, I now understand what it's doing and the rationale behind it.
As much as I've got to like Cura's simplicity and ease of use (even in Expert mode which I am certainly not!), it's a shame it doesn't have similar capability as to what PrusaSlicer appears to do, that is, see both components (it calls them parts) in the single STL and when combined, slices them both as one.

Cura 5.7 is here and it brings a handy new workflow improvement when using Thingiverse and Cura together, as well as additional capabilities for Method series printers, and a powerful way of sharing print settings using new printer-agnostic project files! Read on to find out about all of these improvements and more.
S-Line Firmware 8.3.0 was released Nov. 20th on the "Latest" firmware branch.
(Sorry, was out of office when this released)
This update is for...
All UltiMaker S series
New features
Temperature status. During print preparation, the temperatures of the print cores and build plate will be shown on the display. This gives a better indication of the progress and remaining wait time. Save log files in paused state. It is now possible to save the printer's log files to USB if the currently active print job is paused. Previously, the Dump logs to USB option was only enabled if the printer was in idle state. Confirm print removal via Digital Factory. If the printer is connected to the Digital Factory, it is now possible to confirm the removal of a previous print job via the Digital Factory interface. This is useful in situations where the build plate is clear, but the operator forgot to select Confirm removal on the printer’s display. Visit this page for more information about this feature.
