I love having a little fidget toy at my desk but they are frowned upon at work. I sought to solve this by making my own functional toy that works as a practical office pen cup! Its memorizing lattice core looks awesome as it rotates and it is low profile enough to fit in the corner out of sight. I designed it both in a tall and short version so that it can accommodate any pen thrown at it! In the future I am going to modify it to use a ball bearing but for the time being it is just the base and the spinning centerpiece.
