Pendant Light Shade #3 (Blue)

Description du modèle 3D

This is a shade printed to fit a particular Westinghouse Mini-Pendant light commonly available in home improvement stores and Amazon (link below). You can put a smallish LED bulb in the fixture. Don't use an incandescent bulb because it will be too hot, of course. It was printed with clear PLA on a BQ witbox using a PRINTinZ Zebra Plate. The blue color comes from running the filament through a Staz-on Teal Blue ink pad (link below). I drilled a 1/8" hole through the pad and it's plastic case. The filament wicks the ink along with it and dries before it gets to the extruder. (I printed some little struts to hold the pad in place on my Prusa.) I got this idea from someone on the Facebook 3D Printing Group, but I don't remember his name. When I get it, I will post here to give him credit (assuming it was his idea). You can do this with a Sharpie too, but the ink pads have more color choices.

The outer wall of the shade is a straight cone, but the inner wall has some waves to it to create some variation in the opacity. It took 11 hours to print at 0.2mm layer height, and guess what, my wife wants me to change it so the inner wall is straight too.

eleven....hours....later....ugh ;-)

I tried a 1/16" hole in the ink pad at first thinking it would need full contact to get the ink, but that created too much drag and the first couple prints failed. So I opened it up to an eighth and it worked great. No clogs or funny smells or anything.

You'll need to file the very bottom corner to take off the sharp edge to get it to fit into the light housing.
