Emisar D18 diffuser: double layered and vented

Pointlessly overengineered diffuser for the Intl-outdoor Emisar D18. No supports needed.

The inner layer is integrated in the 3mf as a second component, so you can remove it in the slicer, if you prefer.

Do consider that the flashlight can get hot while in operation and choose your material accordingly. The vents will not prevent overheating of the material and are a purely aesthetic choice.
