My buddy Spencer put together a great Harry Mudd costume for
Shore Leave 2012 and I made a 3D printed flower for him. It was really quick and dirty and not the best model, but it worked. If you really, really need one the files are on my
Thingiverse page.
It actually printed without supports, although it was a little messy on the back. The original was thinner than I wanted so I reinforced it with some hot glue.
