I created a simple extension pole for the Honeycomb Windmill. It also works with the Torodial Windmill and Windmill Base clamp that were all created by user BamBam Design.
The male part of the pole may need some post-processing to ensure a smooth fit. It must be printed diaganolly to fit the print bed (on P1 and X1 series). I was able to fit 3 on the print bed at one time.
