Summary

Just print the yellow parts:

4x 125mm bar,
2x 150mm bar,
9x bar mount
(everything included in the lights.stl)

and attach all together with some glue.

The light angle of the bars is 30° downwards.

I bought some 12V 8mm "neutral white" led strips (3528) from ebay (http://www.ebay.de/itm/111115650134), separable into 5cm pieces. You need 2x 25cm and 1x 30cm (=80cm).

Connect to the 12V power supply using some 22AWG (0,33mm²) wire.

Enjoy! :-)

There is enough light for some cool videos!
