Inspired by the balancing bird toy I remember as a kid, I designed a sleeker and leaner version. The trick works because the center of gravity of the shape is below the nose, but this means it's susceptible to changes with infill percentage. Low infill will have a slight nose-down attitude. I've found that meshmixer supports seem to work for printing with minor cleanup afterwards. Note that the model with supports is scaled up 8x to print at a reasonable size.
