A springy plane mainly based on Boeing 747 (much simplified)
May be hard to print but it's worth it :)

2-3 walls
5-15% infill
No supports needed
Brim is recommended
You will need a good bed adhesion to print this
Filament should be dry - wet filament can make a stringy print and will have a weaker bonds between layers
I printed it with PLA (PET-G may be better, more elastic) with a brim and Spring-joiner-top
Silk or marble-like filaments are NOT recommended
Spring-joiner-Bottom is for joining the spring coils together on the first layer - will help with adhesion
Spring-joiner-Top is for print stability - there will be much smaller chance that the nozzle with knock off the coil parts ruining the print
You will need to use a knife (scalpel-like) to cut the lines between coils - sometimes using just your nails is sufficient to break the line
You can resize model up - I tested it with 100% and 120%
