A couple of attempts at intentionally-bad designs, according to the philosophy explained in this video: https://www.youtube.com/watch?v=XRaZPSrORzQ (NFSW warning for vulgarity).

The Loch Ness Slug was made in Blender (a program that I've been meaning to get better at for a very long time but which consistently makes me want to stick my face in its namesake). The F'ed Up Sword is made in Fusion 360, which I am a whole lot more familiar with, but I still need to be occasionally reminded that it's okay to f*** things up there.

Might make a spacecraft next, because that's the main thing besides swords that I truly enjoy making in Fusion. If anyone is reading this feel free to comment any ideas on what a "bad" spaceship might look like, something that could land on Earth and the humans would tell the aliens NO ABSOLUTELY NOT GO BACK TO SPACE.
