ohhhhhhhhhhh. Ba Na Na.

I got my first comment about the size of an element I designed, which got me thinking about scale, which got me looking at bananas for scale, which led to this: a banana for scale in a outline style.

It's sized about the same as an average Cavendish banana, and has (fairly accurate) markings for both centimeters and inches.

Probably super obvious: 

Printed without supports

It's size (though, it is 6mm tall)
