I came up with the idea of creating a modular spacecraft with interchangeable parts from a video game that procedurally generates its ships.
This design loosely resembles one of the ships in this game. It is still very much a work in progress as I've yet to design different wing and engine styles, but after around 12 hours of LDD tinkering I thought it was in a presentable state.
Number of pieces:
Wings - 322 each
Fuselage - 420
Total - 1064
