Geometric A-Series Lamp Shade. I'm using it with a large plant grow bulb in it and hanging it over houseplants for the winter. The upper polygons are thicker for strength and so that the light is blocked. The lower polygons are thinner and allow the light to pass through some.
My printed example was with a Matte PLA that I hadn't calibrated for and my part cooling fan malfunctioned so the quality is pretty bad. It still did its job so I kept it.
Printed on my Cr-10s Pro with no supports and a .6mm nozzle.
