Open Source Double Desk v2.0

In previous post I showed the general idea how our double desk will look like, now there are more details. Plan is to design a double desk and then give it to 3rd party company to make it.

I'm still looking on how to do the lighting for this desk. Any ideas are more than welcome.

Here is how it looks like from front:

On the back of the desk there are a few details I'm trying to do for cable management, so please share your opinion about it. Is there some better way of doing cable management?

Download current version of this desk and feel free to make changes to it.
