N-6 has wrong shape about jang-seeder-wheel HOT 5 CLOSED

I saw that one and wondered what the actual shape was; hard to tell without one in hand. If it is teardrop, should be able to use this

use <MCAD/teardrop.scad>;
 
teardrop(radius=6, length=20, angle=90);

Thanks! I'll try this. Didn't know OpenSCAD had a standard lib.

Didn't work out, but I came up with something that should.

Reason: MCAD's teardrop shape is, essentially, a circle with a radius-sided square attached. There's no curviness to it as it comes to a point, which is clearly there on the image. I composed something out of truncated cylinders that looks good.

Mind, I'm not entirely happy with it; I'd much rather figure out how to do beziers or functions to get what I want, but I'm hitting a bit of a cognitive wall.
