I wanted to pay tribute to Leonhard Euler who was one of the greatest, most prolific mathematicians in history.

The number e is a mathematical constant approximately equal to 2.71828 that is the base of the natural logarithm function. Although discovered by Bernoulli, Euler is the one who first figured out its value and properties. The number is known as Euler's number.

This pen stand uses the base equation of y = e^x and wraps it around a circle, 24 times to create the shape of this beautiful pen stand. A constant hourly reminder of the importance of Euler and the natural constant e. 

Printing Note

Simple print, 0.2 mm layer height, no supports, even regular PLA works. A longish print due to the complex geometry.
