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)
The author marked this model as their own original creation.
