hovercraft Mk2

A major development of my first hovercraft (https://www.thingiverse.com/thing:2794931)
The MK 2 is
3 cm wider
The lift and thrust fans have a 5 cm larger diameter (150 mm)
Thrust fans are ducted
The whole thrust fan turns on a bearing instead of using fins
Its more aerodynamic
The skirt frame is attached to the body

I have not made this yet but I will update it when i do
