Customizable Duct/Pipe Adaptor (small printbeds too)

Connects any fan to duct. Shown is 120mm fans to 100mm duct.
Has a flange on one side and a tube on the other.
[edit: - now with circular flange option and rounded corners]

Originally derived from dcartoon's excellent 120mm Duct adaptor.

Cleaned up and extended to be customizable.

Now with:

• full or quarter printing (small printbeds),
• overlaps for easy F6 creation,
• added lip to make it easier to cable-tie or attach the ducting,
• circular or square flange shape,
• rounded corners option for square flange.
• if 4 pieces then:
  • overlaps are curved and fit well,
  • strain and fitting relief channel at joins. (see closeup image)
