Altering you perspective view so that you can see in only the plane you wish to move it in is a good idea, otherwise you will not rotate accurately. The second click almost produces a handle by which you can rotate the object in the desired plane. You will need to click on the rotate button, then click on a face of the object you wish to move and then click away from the object.

So select the plane that you would like to move the solid in and then go back to the Draft workbench and use the rotate button. You can find this by right clicking on the solids which brings upo the contextual menu.

So nearly there, we need to now position the text on the cube. ) but we thought that adding some text to your freecad model, specifying the axis is a good idea, it allows you to know which way the cube was printed so you can trouble shoot problems with specific axes.

The first thing you will need to do is select the Parts workbench. The first thing that you will need to get to grips with is Freecads use of Work Benches Different work benches have different tools and these different tools can operate on different sets of object types. So first things first open Freecad and create a new file. Inkscape (or suitable vector graphic program that can produce.

Inkscape for 3d printing
