Lego Technic Pins
thingiverse
draynnov83's pins have tiny holes in the middle that make the cross-section a little strange and they are a bit faceted, so 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 I used to make each pin. To make your own pins make the cylinder the length you want (8 mm per lego stud), center the disc and wedge (make the wedge a hole) on the ends, and put the doughnut in the middle for the stop. To print I put one every 6 mm in Cura so they just touch and it seemed to work well.
