[Facelesstech] also designed a compact 3D-printed case that packages up the Arduino Pro Micro along with an ISP header for easy updating. The case even lets the Arduino’s power LED shine through ...

This is a very simple hack: an Arduino sits inside a 3D-printed case that holds a big, red button. The case itself is very sturdily made to withstand a good satisfying smack: it has thick walls ...

My goal with this project was to be able to dynamically know the filament status during the 3D printer operation. I developed this project by mixing design, 3D printing, electronics, software, and of ...
