The tree consists of two hinged MDF half sections that fit into a steel alignment bracket on the floor which makes it very stable once erected. Each quarter panel of the tree was laser cut in 18mm MDF from four different DXF files. The two quarter sections of each half section are attached together by hinges. Each half is free standing when it is opened up to 90 degrees.
After each half is opened out to 90 degrees is fits into the steel alignment star as shown in the photos below.
