This KDE plugin provides thumbnail support for sliced MSLA file formats on Linux, including .goo, .ctb, and .nanodlp files. It displays the embedded preview images as the file icons (using the mslicer format implementations).
Check it out on Github at @connorslade/msla-thumbs.

First you will need to register the .goo, .ctb, and .nanodlp formats on your system. Download the XML files in plugin/mime and register them on your system.
Next, download msla-thumbs.so from the latest release and copy it to /usr/lib64/qt6/plugins/kf6/thumbcreator/. If using the Dolphin file browser, you will need to enable showing 'Sliced MSLA previews' in Configure › Interface › Previews.
