This is a 3D printed bowtie! It's designed to be segmented. This way it can be joined by string and flex, plus you can print it in different colors.
You can check out how I assembled it here: https://youtu.be/WKoOM_OGp5c
Most pieces don't need support if printed with the flat side down. I do however recommend supports for the innermost segment of the bow part.
Glue the center sections and thread each lobe to it one at a time using fishing line or stretchy jewelry string.
Finally, Glue the clip if you want to wear it as a bowtie or don't if you want to glue it as something else.
