Hello,

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.

see attached sketch

best regards

There is no need to print the model, you can measure segment volumes in model (using “Segment Statistics” module) much more accurately than in a physical model.

You can draw tubes in the segmentation using “Draw tube” effect (provided by SegmentEditorExtraEffects extension).
