Hey there,
This topic kept me interested as not-registered user for several months now, as I am considering to light up my modulars a little bit, too. I am really impressed of the detailed and precise work!
A short question regarding the 3mm tube you are using to cover the cables (you wrote about in the thread-opening-post).
Is this a Lego-original brick or third party product? - If so, where did you get that?
Kind regards,
Stonehenge
