8-Bit 3mm LED Holder

thingiverse

This compact tool is designed to keep 8 tiny LEDs perfectly aligned on a breadboard. When placed side by side, they often become disorganized, sometimes even switching positions. Simply slide this gadget onto the board (a little tweezers trick helped get the LEDs into place), and it will keep them straight and in order for you. I've added before-and-after photos to showcase its effectiveness.
