A heavy duty 43mm or smaller light post mount. I have a waist high wood fence made of 4x3" posts this is designed to screw into the to of these post and basically be permanent. a large printed grub screw goes into the side to secure the light (such as nice heavy higher end solar lighting)
Suggest 6 perimeters 25% infill “NO” bottom layers (drainage) PLA is fine just don't use dark colors and paint is a good idea. Mine are printed in Atomic Filament PETG. They are essentially unbreakable. you would have to hit them with someone to break them and then you have more to worry about than the $1 print :-)
you only need one print of the driver (giant screw driver) then just print a base and S/L grub screw (L for smaller diameter light posts)
