The new version of Cura has come out and it has a whole bunch of great features, but what got me most excited is the ability to split a model before printing. I was looking for a feature like this and was considering using OpenSCAD to modify the model file, but that's impractical in all cases, with Cura you can do it with a few clicks now.

To do this, load the model into Cura, right click the model and choose 'Split'




After the model is split up, individual parts of the model can be manipulated. Here I select a part and delete it, but it's also possible to move it on the print surface.
