Forrader/UltraFire C8 adapter for gBeam

An adaptor to mount the forrader cree XM-L2U3 or UltraFire C8 to the GuerillaBeam.
If you wonder about the long tube: I made it a bit longer, with the first, shorter version, the "shadow" of the led was visible in the projection.

UPDATE: VER2 added:

Because of the long tube, the gap in it bend open when srewing the torch in tight. So I redesigned the adapter for a better fit.
I took the chance and enhanced the thread at a single blow. Universalist had published a drawing of the thread
