Well there is Appinage or Flatpak. Either one of those.
You can run appimages in Tails
Enable Administrator password on the menu screen, create a persistent storage (if it doesn’t already exist), download the Flatpak file from the website, and run
torify flatpak install /path/to/file flatpak run io.github.softfever.OrcaSlicerUsing an AppImage is not a good idea because they have a tendency to give errors if proper software and version are not installed on Tails (on my Tails USB, this was because of GCC) unless you compile your own AppImage. Using Flatpak is better as it allows you to run software on your system even if the versions of GCC etc. are not up to date.
Please keep in mind that I have not confirmed whether this method is secure and would advise that you consider whether this is secure or not depending on your threat model.
