“A Pen Holder made from PCBs and 3D Printed parts in an OverEnginnered Way.
The concept of this story was that after using a mug as a pen holder for some years, it was time for an upgrade—an OverEngineered upgrade.
I utilized four square PCBs and a few 3D-printed components to create a new pen holder. Three PCBs are only there for aesthetic purposes, but the one on the backside of the device has a power management IC that is being used to operate any 5V device, such as an Arduino board, or even charge a smartphone.
It also has a few RED LEDs that light up the entire system and make it appear like a lamp in the dark.
A 3D-printed pen holder would be easy to make, but where’s the fun in that? This pen holder’s overengineered design and built-in battery boost its usability and visual appeal, which in my opinion, makes it far superior to a pen holder that is entirely 3D printed.
This article is about how this project was built, so let’s get started.
