Lego bb0219 - Train track stacking pin

A simple replacement part for the stacking pins originally gotten with RC tracks. These are often thrown away early, only to be remembered as handy later on when storing tracks again.

The hole for the pin seems to be made 3.1mm (caliper measurement), with this pin being 3.0mm.

ACCURATE  Z Calibration needed when printing upright!
Try using negative Horizontal/XY Expansion if it's not fitting, or positive if it's not a snug fit.

Made in Fusion360.
