Pratt & Whitney Aircraft's first engine, the 425 horsepower (317 kW) R-1340 Wasp, was completed on Christmas Eve 1925. On its third test run it easily passed the U.S. Navy qualification test in March 1926; by October 1926, the U.S. Navy had ordered 200. The Wasp exhibited performance and reliability that revolutionized American aviation. The R-1340 powered the aircraft of Wiley Post, Amelia Earhart, and many other record flights.

The R-1340 was followed by another very successful engine, the R-985 Wasp Junior. Eventually a whole Wasp series was developed. Both engines are still in use in agricultural aircraft around the world and produce more power than their original design criteria.

Coaster is 100mm and 3mm thick. Design prints on 2 layers, face down, so as to maximize detail. If you move the prime tower, you can easily fit 5 of these on a 256x256 build plate. 3D Model is of the logo itself. Disc was added in Bambu Studio to create the coaster.
