Custom TT-bar bridge

Hi,
I am planning to build a custom TT-bar bridge between the extensions. After thinking a bit, the idea developed so that I am planning to put di2 on my bike and I'm going to hide the di2 cockpit junction box SM EW-90 A to the custom bridge. The bridge is going to have open sided 'box' for the junction box. Now I need your help and if you could send the measurements of the junction box I would be very pleased with that.

PS. Sorry for my English as it isn't my native language. :)

Which bars do you have? There may be a nicer way to do the junction.

I have 3t Vola team, I'll try to find photo.

What do you mean by nicer way? I would really like to know.

Thanks for answering and nice looking bike. Yeah, the problem with the stock bridge is that I can't get it enough narrow for my position. Have anyone drilled their Cervelo P-series seatpost for Di2 cables?

I have also some special Drag2zero armrests and wedges, that's why I also need custom bridge.

Your original post seemed like you didnt have a bridge at all, I'd say some 3k carbon plate cut and drilled would be the best solution for the bridge itself then mould the cavity using 3k mat and resin.

Sounds good, do you anyone who can build carbon plates and cavities?
I need to have separate bridge instead of the bridge which I have know made from the armrests. Now the armsrests measure too wide to the UCI-rules and next year I am racing in the bigger races where the commissaries are very strict.
