Cannot use "Open in Slicer" button on printables.com. Could not read file orcaslicer:// & Unable to create KIO worker. Unknown protocol 'orcaslicer'.

I am trying to quickly open 3D models from printables.com in the slicer program “OrcaSlicer” to process for 3D printing.

To skip the hassle of downloading and importing a model file, the site offers a quick “open in slicer” button for PrusaSlicer, Bambu Studio and OrcaSlicer, all of which share a codebase.

The Button opens an orcaslicer:// URL that should get passed to OrcaSlicer.

It however throws seemingly random KIO errors:
First I got “Could not read file orcaslicer://open?[….]

So I tried to manually associate the url type to OrcaSlicer using both a seperate desktop file and a file association in KDE settings.

No luck with both. The error message just changes to “Unable to create KIO worker. Unknown protocol ‘orcaslicer’.”

How can this be fixed so I can use the “Open in OrcaSlicer” button? It works fine on a computer running windows.

FWIW this works for me with Prusaslicer. If it’s not working with Orcaslicer, it would appear that the OrcaSlicer isn’t registering the orcaslicer:// URI handler properly. I can’t test with it because it isn’t available on Flathub.

PrusaSlicer from Flathub works for me aswell, but I am entirely unsure how it works.

For info, I am running Arch Linux and using the OrcaSlicer package.

If OrcaSlicer doesn’t register the URI handler properly, how can I do that manually in the system? I tried to and failed as outlined in my first post.
