Hi everyone.
I've been recently learning about three 3D rotations, Euler Angles, Gimbal Lock, and related topics.
Thus, I really wanted a Gimbal in FreeCAD to help visualize exactly what was going on when editing Euler angles in the Placement dialog -- as it's not always very intuitive.
I threw together a Macro that creates a Gimbal, via a scripted object, in the document and can be arbitrarily linked to any object (via App::PropertyLink):

It's a little rough, but I thought it was functional enough to share.
Let me know what you think!
