No fancy CAD work here, but I certainly want to share!
I have a cheap Desk Lamp with 52 LEDs, but IT'S WAY TOO BRIGHT!!!
So, I made a set of dome diffusers with White PLA to save my son's eyes and soften the light.
THIS IS ALSO VERY USEFUL FOR PHOTOGRAPHY APPLICATIONS!!!
Don't forget, though, you may Scale this to fit your application!
3 Styles: Short (1), Hemisphere (2), and Egg (3)
Da Vinci 1.0 PRO (+E3D V6)
Scale to fit your desired size.
Low infill, since you want more light to pass through.
Use a Brim. 5mm works for me.
Try to avoid using a heated bed. It can trap heat inside the dome and create problems at the end of your print.
