Lidar-Lite shield tube

The PulsedLight Lidar-Lite is a compact device that shines bright, but I've found my unit emits a significant amount of infrared light outside its main axis; some internal scattering may be at play. This means a nearby surface can still be detected by scattered illumination, even if it's not directly on-axis. To minimize this effect, it wouldn't hurt to add a sun-shade in place, so I've designed one. The wall thickness is 0.8 mm and works best with a 0.4mm print head when infill is set to 0%. An OpenSCAD model is included. UPDATE: Version four features more baffles (# of rings is adjustable) and improved mechanical fit to the Lidar case. It's worth noting that many plastics are translucent at 900 nm, and I could even see the beam through the wall with an IR camera before I painted it. To work as intended, you'll need to paint the inside with a flat black opaque paint (I used "Angelus Brand Acrylic Leather Paint"). This can be tricky given the internal baffle rings, but an old toothbrush worked well for applying the paint.
