NOTE: If you're using the .desktop file to start the program, Openscad will try to link your system Qt libraries. This is done to enable missing (dark) themes. If you get undefined symbol errors, make sure the required Qt(6) libraries are installed on your system. Alternatively, create your own .desktop without QT_PLUGIN_PATH and LD_LIBRARY_PATH.

Thanks, the get-latest.py is a very convenient way to get the latest AppImage, actually!

Hi @Felixoid, thanks for your comment. I've included your MIME suggestion, that's a good one. It didn't occur to me because I never see or click file icons (I use arch btw). I've been using a (terrible) python script (included in this git repo) to automatically update the content, which I run periodically. Due to life, I hadn't done that in a while now. I've added you now as a co-maintainer, so feel free to update it if I take too long :).

Do you need help with maintaining the package?

There are a couple of improvements necessary for comfortable usage:

• update the packages
• extract the mime directory to open files properly using OpenSCAD
