This bowtie prints without support. There is a slot in the back which will fit over standard shirt buttons.
If you want to change the colors as I did, watch your print around 46% when and change the filament when you see it start to make the inner perimeter. Then change it again around 97%, once it is only printing the center knot. I finished this one off by coloring the remainder of the knot with a sharpie.
