Philips 14w LED A19 Shield

thingiverse

I have a spacious area in my unfinished basement where we've set up several couches and a massive 145" projection screen. We love to watch movies down there with our kids and their friends, but no one enjoys watching in complete darkness, especially the kids. The problem is that the lights in the basement are bare bulbs shining directly onto the screen. I used to try and staple cardboard just right in front of the bulbs, but it was never very effective. Then one day I got a 3D printer and came up with this solution. This shield snaps onto the base of the bulb and can then be rotated to block light from hitting the screen. When we're not using the projector, it can easily be removed, allowing light everywhere. Please do not use this shield with incandescent bulbs! Print Settings: Printer: Monoprice Maker Select Mini Rafts: Yes Supports: No Resolution: 0.25 mm Infill: 20% Notes: I printed it in PLA because that's all I have. If you have PETG or ABS, that would be better since the 14w LED bulbs put off a fair amount of heat. It won't melt the PLA, but other more heat-resistant plastics would definitely be better. The width of this shield is what's required to block the correct amount of light based on the distance of my lights to the screen. If you're using it, it may block more or less than what you need. If you want the Fusion 360 file to customize this, just message me and I'll see what I can do. It might be nice if someone built this with OpenSCAD and parameterized it.
