3D model description

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 the light.

The model is exact and does not consider shrinkage of the plastic when it cools down after printing. For ABS, you should typically upscale the model before printing to 100.7%, for PLA 100.3%. If you don't do this, it may be too tight and break when you try to mount it. Of course, you may also need to apply an additional scaling factor if your bulb is not exactly 45 mm in diameter.
