Hi Again . i brought the rod from our local steel supplier it is 6mm round bar i did the design myself the normal stars the wiring is the same as the Boscoy 46 - 3 layer star. and the Bethlehem star is a GE starburst basic wiring think it is 187 nodes the pixels are mounted with plastic pixelclips connected to a 30mm rod welded to the main frame .cool, have you got a post on where you get the rod and how you join it? I would love to copy that design if you don’t mind.
