Parametric Gimbal, prints already assembled

This neat printable gimbal prints already assembled on Replicator 2 printers at least, and optionally can have a ball bearing ball weight which clicks in to place, creating a fairly effective gravitovectometer (like an accelerometer, but only gives you a vector, not a rate, and yes, we did make up that word)

It's just a nice thing to have and to play with. You can hold a gimbal up and blow on it and the middle two parts will spin around crazy fast, with the center part stabilising very quickly at a 90° angle to it's parent like a gyroscope. It could potentially be a neat tool for explaining gimbal lock to people learning 3d graphics too.
