I have printed a vessel model (3D) and would like to use the main branch (approx. 5.6mm) with a syringe /cannula (approx.3.5mm) to introduce a liquid to determine the volume of the vessel.
My problem is the transition from the main branch to the syringe/cannula. Is there an idea for this?
One could also provide a cover with a precisely fitting opening for the cannula when designing the model.
It is important that no liquid escapes, otherwise the result would be falsified.
