Lego Technic Pins

thingiverse

draynnov83's pins have tiny holes in the middle that create a unique cross-section, making them slightly faceted. To replicate these pins, I copied the angle of his pin slot and redesigned the rest using max facet cylinders in Tinkercad. I also included the .stl file for the pieces used to make each pin. To manufacture your own pins, create a cylinder with a length of 8 mm per Lego stud, center the disc and wedge (transforming the wedge into a hole) on the ends, and place the doughnut in the middle as a stop. When printing, I placed one pin every 6 mm in Cura, allowing them to just touch each other. This approach seemed to work well.
