Syringe-vial spacer clipon V2

thingiverse

Here another version my idea to adjust the syringe needle penetration depth into the vial to allow best possible extraction of the liquid inside. Maybe simpler, just clip it on top of the vial. I made many different diameters. I just dont know what length it needs, since it depends on the needle you use. just scale the length axis before printing or tell me what length you need.
