I designed this decorative support structure to protect dangerously sagging glass shelves on my TV cabinet.

It prints without supports and you can just scale it to what ever size you need it in your slicer.
The stl base measures 150 x 150 mm and it is 120mm tall.

Fun fact: This shape is simply a combination of mathematical functions.
