Cura

Cura was the first slicer I used for 3D printing, and I’ve stuck to it over the years because it has excellent multi-platform support¹ and a sprawling ecosystem (including OctoPrint integration and a number of useful plugins).

Although I am becoming more and more partial to SuperSlicer, I still use Cura because it has a better slicing engine (Arachne), but I find its accordinon-like parameter editor increasingly cumbersome.

This is the .desktop file I use to launch the Cura 5.1 .AppImage in Fedora 36

#!/usr/bin/env xdg-open
[Desktop Entry]
Version=1.0
Terminal=false
Type=Application
Categories=Graphics
Name=Ultimaker Cura
Exec=/opt/ultimaker-cura/Ultimaker-Cura-5.1.0-linux-modern.AppImage %U
Icon=ultimaker-cura
MimeType=application/vnd.ms-package.3dmanufacturing-3dmodel+xml;application/vnd.ms-printing.printticket+xml;model/3mf

For version 5.0, you had to give the appimage a little hand in finding some runtime libraries:

Exec=env LD_PRELOAD=/usr/lib64/libstdc++.so.6 /opt/ultimaker-cura/Ultimaker-Cura-5.0.0-linux.AppImage %U

The .desktop file should go into .local/share/applications, with a suitable icon alongside in the icons folder.
