This is a cap for DIY badge pins using regular needles and pins. I made this because I did not have any of the thicker pins made for this project, so I instead cut up regular pins and glued them on the backs of my badges.

Again is 0.9 mm and again but bigger is 1 mm, so hopefully one of those work. I made the badges/pins by laminating paper in hot glue, and I glued the pins on with epoxy.
