Inspired by the Star Trek TNG combadges.

This design is made out of three parts and can be printed on three different plates, so it does not require an AMS. 

It is easy to assemble and does not require any glue or additional hardware.
I added three ring sizes with 4mm, 5mm and 6mm holes. Hopefully there is a suitable size for everybody. If you need a different size, please let me know in the comments.

Assembly (also see pictures):

1. Simply select the ring size you need and push it into the rectangular hole of the oval. (this will take some force)
2. Then push in the arrowhead in the recess of the oval until it snaps in place. And you are done!

There are two print profiles. One is with  all the parts on one plate printed by model. The second profile is separated into three builplates for printing without AMS.

Most drawstring beads come in pairs, but that seemed wrong to me here. So if you have an idea for a nice model to go on the other end of your hoodie drawstring, please let me know in the comments.
