Reflector for E27 lamp

Crude but functional and easy to print reflector for LED lamps with E27 base. Some important points, please read all of them.

* Maximum diameter of the lamp base is about 39 mm, which is roughly 1.5". That means lamp bases that are threaded on the outside typically don't fit.

* This is designed to hang, or, stand like on the cover glass of an aquarium or terrarium, if you have it standing you need some kind of stand offs, to let air in, the design relies on convection cooling. The design also uses the bulb to keep the reflector in place when it hangs, so it might not work with every type of bulb shape.

* It is designed for low to moderate power, high efficient LED lamps, that are also low weight. The highest wattage lamp I have tried so far is just over 10 watts, and that has worked without problems, but you should absolutely check your own reflector. I take no responsibility for anything. You know, mains voltage, heat, plastics, possibly fire, use your brain.
