They charge $30+ for sets of these at the hardware store and they come in almost no colors. I put together this little shade for a 3 light fan, not sure of the manufacturer.
Be sure to ONLY use LED lights. Incandescents can melt stuff and if it melts you could have problems. I used PETG to further protect against that. If you can touch the bulb you are using after it being on a while you should be ok.
Printing set detect thin walls to on, no supports necessary. Thinner side down.
