Created this for Bam Bam Design's Hexagon Windmill model. It is also interchangeable with the Sunflower Windmill as well!

The male part of the pole may need some post-processing to ensure a smooth fit. It must be printed diagonally to fit the print bed (on P1 and X1 series). I was able to fit 3 on the print bed at one time. I recommend using PETG to avoid failure while using in high winds.
