I made this little dispenser tip in order to inject adhesive in hard to reach places. It's essentially a copy of one I had.

The dimensions are based on the existing tip and the Luer Lock ISO 594-2 standard. These dimensions were then tweaked to get good final dimensions with my Ender 5. I tested the dispenser on 3 different syringes and it fits on all 3. This design should technically fit any syringe that follows that standard.

Tip: If the print is not water tight, a bit of clear nail polish on the outside seems to do the trick

Have fun!
