My wife wanted science fair trophies for work. I loved the shape of the model but needed to add text, but I am really bad at modifying STL's. This uses two ¼-20 thread inserts and two 1/4-20 button head screws to assemble. I did this to add weight to the bottom, ease of assembly, and to make them stronger.

The author remixed this model.
Rebuilt from a profile of the model, 3 different parts with hardware and tolerancing. Also providing fusion files.
