Coffee Cup Hook based on Phi

A coffee hook designed to work with 3M Command Strips. Fusion 360 files included.

My first design worked, but wasn't very pretty, so I went in and based as many dimensions as I could on the proportion "Phi". If you are not familiar with Phi, Google it. It's very interesting and is found many places in nature. It is also related to the Fibonacci series, also found in nature.

The length and width are proportioned by Phi. The position of the base of the hook is proportioned to Phi based on the length of the base. The Diameter of the base of the hook is proportioned by Phi to the width of the base.

It's very strong. Printing on glass is recommended as it requires a very smooth base for the 3M strip to stick. I printed on Anycubic's version of Build Tak because it came with my printer.Also, I used lines as the first layer fill, but then switched to concentric for the rest to make the model surface smooth over the curved surfaces.
