Alignment microscope for drilling 3D printer nozzles.

I normally drill a nozzle by setting it up on some form of holder in a drill press and carefully adjusting the position, repeatedly inspecting from two positions at right angles to each other. As I have a lot of nozzles to drill, I felt the need for some visual aid which would allow both views to be seen simultaneously. Fortunately 3D printing let me build a device very quickly - and the ready availability of cheap USB microscopes didn't hurt at all.
