45 mm round lightbulb diffuser

This is a simple diffuser that snaps onto 45 mm round light bulbs. You can use this to reduce light output or change the tint of the light.
Obviously, this is *NOT* to be used with incandescent bulbs, only with LED bulbs! For high-powered LED bulbs that get hotter than 60°C, you may also want to use a more heat-resistant plastic than PLA.

It comes in two versions, one 1 mm thick and one 1.5 mm thick, which one you want depends on how opaque your filament is and how much you want to influence
