Based on Derekbackus' design of his MiniTree made of steel, we have adapted his design to a cost effective coro version.
The Large Version of Derek's Dalek MiniTree uses panels with 17 Pixels/RGB nodes for a total of 85 nodes in a 180 degree configuration. You can install as many or as few nodes as you like. The tree also includes our 12" 20 node star that is held in place with two nodes and reinforced with a steel rod.
The inside of the tree has the score marks for folding. Install pixels or RGB nodes of your choice. Take the star and install the metal reinforcement rod if it isn't already installed, make sure it is in a channel that doesn't obstruct a node mounting hole. Then bend the star mounting tab slightly just below the star to make it straight when the tree is complete and it keeps the reinforcement from falling out. Make all wire connections now. When you are ready to close the tree, install the zipties loosely until you have them all in place then you can tighten them up to make the tree close.
