So due to needing to eat outside, I’ve been modifying our landscape lighting to let people safely walk around the house to our backyard in the dark (normally who would be eating on their deck in December when it is super dark by later afternoon, so who would have worried about this). So I installed a bunch of the LED spots to light the path back. The problem I had was that the lights were so glaringly bright. I had one set of older lights that had shades and one new set that was 1/2 the size but just as bright without a shade. So I first found that mounting them higher off the ground made a huge difference in how well they lit the path, which meant my neighbors got a lot of glare. So after 3D printing shades for the lamps which helped a smidge I realized I needed a hex-grid to keep side-glare down. The smallest tilt down eliminates the glare forward, which was perfect.
In hindsight I should have laser cut the grids as the 3D printer didn’t like such thin walls (in fact the slicer threw them away as “noise” until I turned on “detect thin walls”, but they were prone to print failures. The part friction fits on there making a perfect use for 1/4” black acrylic (these lights are small enough to use a lot of scrap black acrylic I have around). It will be way more UV stable vs. the PLA I printed the rest of the stuff with. I do need to make some more, so figure I will do that, since it will also take way, way less time!
