The model is designed to sit over the top of an LED tea light and make it a feature.
The trunk is a stepped cylindrical cone using a translucent or transparent filament to enable the light to shine through.
The leaves are green to identify it as a tree during the daytime but again using translucent or transparent filament.
Assembly requires no glue, the 4 leaves fit into slots at the top of the trunk and a cap also with 4 slots to align with the leaves sits over the top and simply presses into place.
