This design is for a top mounted flagpole light.

It is designed for the Allied Flag spinning flag pole: https://www.amazon.com/gp/product/B00DIA75Q6/

It is also designed for these solar yard lights: https://www.amazon.com/gp/product/B01HXN01BE/ , but may work with other lights having similar design.

This has a 47.5mm diameter spherical socket and a 34mm diameter tubular base.

Krylon Fusion white spray paint was used to paint the bracket and solar light.

The pole bracket was designed in Onshape and the solar light interface was designed in Fusion 360. Both were sliced in Simplify3D.

You will need to re-orient the parts in your slicer as shown in the image. Supports are required.

You will need six 3/4" or longer #6 screws and nuts (or 20mm m3 screws and nuts).
