I’ll demonstrate how I built a worm drive pan/tilt mount out of Lego for your various Lego optics lab lens and filter holders. Some folks might find that the worm drive allows a bit more fine tuning for the rotation and tilt of the lens or mirror mounted on the worm drive pan/tilt mount than they were able to do using the simple pan/tilt mount.
