For a particular task I needed to co-align two battery-powered laser beams and steer them in two axes, in a small form factor envelope. I designed and 3d-printed this doo-hickey which worked great.
The part near bottom right is the dual-axis steering mechanism using two plastic tension springs controlled by set-screws. Batteries are the grey cylinders, and the lasers are in red.
