Star Pin

You can print this part and glue these metal pins to it:

For extra security you can also print the circle part and glue it to the other side like in the Picture.

I also painted these for the purposes of my Costume. The Star has a diameter of roughly 40mm.

Lastly, if you have questions, want additional file formats, have a Commission, or just want to nerd out about 3D Printing stuff:
