This is really nice.
Is there any advantage of having the "nozzle" of the syringe off centre? The one you printed is centred, but the STL files have it slightly offset. I have seen this on injection moulded syringes, so I doubt it's a mistake on your part.

This is probably the official answer: "Eccentric tips are best for when you need to inject a medication parallel to the skin of the patient. It is used also when you want to inject into a vein near the surface of the skin." --https://www.vitalitymedical.com/blog/selecting-syringes-and-needles.html

The only advantage I can think of is that it helps to apply the fluid more precisely if the nozzle isn't obscured by the syringe. Too far off center, though, and it might be difficult to fully drain it. So the shown position is a compromise.
