Summary

This is a railroad signal inspired by Duplo railroad crossing barriers. The beams and the base are compatible with their railroad crossing counterparts.

The base part prints without supports.

The beam will need minimal supports on the base only if printed vertically.

The red circles are separate objects. Just glue them in.
