It's mainly helpful for modelling techniques using Blender and SketchUp. It also shows use of Prusa Slicer for doing simple modifications to STL files.
There are also a lot of videos about automation using Arduinos, more relevant to a different SIG. Tip of my hat to Graeme Dunbar who alerted me to this channel.

Thanks, I have never tried Prusa but will give it ago.
