Lampshade v.5

Next version of lampshade from me.
Inspired by lily on the valley flower.
Lampshade consist of two parts: main body and separate washer. This allow to make good fixation without broking of fragile body.

Update 18 February 2016:
Old washer file has been deleted.
Two new files have been uploaded for E14 and E27 lampholders.
You can print two copies of required size and fix lampshade between them.
