Lamp shade scalable

I found that lamp shade (https://www.thingiverse.com/thing:2723000) some days ago. But it did not fit E27 bulps and was also a bit tricky to print.

So I redesigned it and split it in 2 print parts. These are easy to print.
Also they are now scalable, so you can decide how big the lamp shade should be and by resiziing the fixture how high or low it sits on the lamp.

The 2 parts are simply stuck together. Please don not use glue, as you will not be able to reach the light bulb any more.
