I needed to apply silicone to the joint of ceiling and wall.

I used small syringe to do that.

The syringe nose was not optimal length nor width.

I created one.

You print and just plug it in.

For standard syringe heads. ~4mm+ inner diameter of the 3D modeled cap.

Cap is quite tight which is what you want so it stays on.

In the syringe in the picture is tapped which makes the cap grab really tightly. Would work with normal syringe too.
