Update: I've got a newer version to print parametric support-free breast forms! Check it out here!

This is a basic breast form design that I use to shape and fill fabric forms, but can also slip into a bra as well!

Print like a bowl, supports can be sanded down. I don't have a flexible filament to see how that would work, but I am curious to see how that would work!

You might want to scale it to fit as well.
