The "Open in PrusaSlicer" functionality on Printables doesn't work

[DominikPalo]

Description of the bug

The new "Open in PrusaSlicer" functionality on Printables doesn't work as expected. After clicking on the "Open in PrusaSlicer" button, the PrusaSlicer application is opened but no model is loaded (the workspace stays empty)

Example URL: prusaslicer://open?file=https%3A%2F%2Ffiles.printables.com%2Fmedia%2Fprints%2F380760%2Fstls%2F3195166_b73bacc6-cc1b-4058-bc26-2b349b193229%2Fgeneral-pavel-flannel.stl

Project file & How to reproduce

1. Open any project on Printables.com
2. Go to the files tab
3. Click on the "Open in PrusaSlicer" button near any STL file
4. PrusaSlicer app opens, but it doesn't load the STL file

Hello, @DominikPalo,

Could you check if you have the Printables download enabled in Configuration -> Preferences... -> Other -> Allow downloads from Printables.com

@Jan-Soustruznik thank you, it wasn't enabled in the slicer config (I didn't know about such an option). After enabling it, everything works as expected. Maybe it would be nice to display some warning message in case the app is triggered by a prusaslicer://open?file=https%3A%2F%2Ffiles.printables.com... URL and the setting mentioned above is disabled.

printables.com says to enable this option when you enable checkbox in user prefs

I am fairly certain that setting enables URI handler in first place, so without it app isn't triggered at all (I think)

@gudvinr in my case not... it seems there is a bug on the Printables.com page or that option is not translated to CZ (so I see only the keys profile.show-prusa-slicer and profile.prusa-slicer-help instead of the text)

@gudvinr that's not true - the custom prusaslicer:// URL scheme is handled by the app even if the "Allow downloads from Printables.com" checkbox is disabled. The URL scheme is defined in the Info.plist file (CFBundleURLTypes key), so macOS associates the PrusaSlicer app with that scheme automatically (it is not even required to drag the app out from the DMG)

To clarify: On both Windows and Linux it really is triggered only after the URL scheme is registered (so like @gudvinr wrote) but on Mac it is just as @DominikPalo writes.
We will look into it so it won't happen exactly what happened here - PS pops up but nothing happens.
Also Printables team was notified about the bug in translations.
