Dan's Hamburgers inspired lamp shade...

thingiverse

I drew inspiration from vintage-looking lamps hanging at Dan's Hamburgers, my local diner. The original photo features the blue fixture, while the red one is my first print. Currently, I've sized it to fit our existing fixtures. My goal is to spiralize the inner cone so that it's a single layer thick and translucent. This design isn't specifically intended for incandescent lamps; however, LED ones should work just fine, which is what we use.
