This is a twisting lampshade based on a Koch Snowflake fractal. It is use with LED lights for cool operation. I made these with PLA but consider using PETG instead for a higher thermal margin. There vents on the top for warm air to rise and exit. They are about 200 mm in height. They are kind of narrow, so to screw in the lightbulb put the bulb in the shade first with the threads sticking out. Grab the bottom of the bulb from the outside of the shade to screw it into the socket. Make sure the switch is off.

There are two different versions of this shade, 1 and 1a. The only difference is the bottom. Choose the one that fits your lamp best.

I've made a few other lampshade designs. Check them out in my Lampshades collection.
