Some additional beams for Torsten's "Webcam holder for Ultimaker" thing

Note: This is thing is not maintained on here any more, further development/support it will happen on its Youmagine page.

You can find the original webcam holder here.
I wanted to position the webcam in the upper corner of the printer to get a nice view of the print bed. For this I needed to additional beam types: one turning the screw holes by 90° and thus allowing a "change in direction" in the beam construction (directly attached to the frame attachment in the picture), and one L-shaped beam allowing to screw a regular beam in on the top (attached near the camera in the picture).
Publishing since those two new beam types might be of help to others too.
