GEVs, or ground effect vehicles work by harnessing the ground effect when near the surface. Pilots have long reported their planes "not wanting to land" when touching down. This is caused by the air beneath the wings compressing, therefore increasing the efficiency of the aircraft, as it does not need to exert as much energy to stay aloft.
There are three main types of ground effect vehicles, on the one I've modeled, the wings touch the ground on all surfaces, so when air is pushed into the cavity, there is nowhere to go. Therefore it has to move the plane up to create a small area for the wind to leave.

How to print:
Repair the model in your slicer by clicking on where it says model error (this is because the model was designed in Blender)
Move the model down a bit to ensure all surfaces are touching the floor.
Split it apart down the middle, and print the two halves.
