Brio Pin Connector Replacement (4mm base)

thingiverse

This small connector for Brio train rail is a new version with a 4mm diameter at the base. So it's a little bit smaller as the one from *markosaurus*. It seems that Brio has different sizes. ## Printing Hints * Print the pin laying on the side (turn 90 degrees) with support * Layer height: 0.15mm (worked perfect for me) * My print was slightly smaller then 4mm and fitted perfectly. I glued it into the hole in the rail.
