Lidar-Lite shield tube

The Lidar-Lite from PulsedLight is neat widget, but I found my unit sprays quite a bit of IR outside of the main axis of the collimated laser beam; some internal scattering maybe. As a consequence, a nearby surface can be detected by scattered illumination, even when it is not on-axis. Also, it wouldn’t hurt the receiver to have a sun-shade in place, so I designed this. Wall thickness is 0.8 mm and with a 0.4mm print head, it works best if you set infill to 0%. OpenSCAD model included.
