STL (3D Model) – $3.00 USD
This is an STL file for your 3Dprinter of the British WWI aircraft Martinsyde G100 Elephant.
Designed as a fighter and zeppelin killer, the Elephant was not a success. Not particularly fast and maneuverable as a paperweight, the performance of the G100 was lacking.
However, pilots liked its ruggedness and easy flying characteristics, and this proved even more so when the type was turned into a single-seat bomber. She excelled in that role, and served in France and the Middle East.
The model is scaled at 1:100th but may be printed successfully at smaller or even larger scales (though with a corresponding loss of detail) depending on the quality of the printer and type of material.
The download also contains a 1:285 scale version.
