Started as an attempt for SHIPtember 2023, finished just ever so slightly overdue.
The starting point was an experimental rough frame sketch using only znap pieces, no technic beams whatsoever, which was then reinforced with stacked plates all around (and on some internal nooks and crannies).
For 10.5 kg of plastic, the end result is surprisingly strong, stable, and swooshable.
For the exterior, the curved front section with trilateral symmetry was probably the most difficult to get figured out, but in the end I'm actually quite pleased with the results (although it took a bit more time than I would've liked...)
