@lassoan for our application we need the model of the actual probe so that we can get the coordinate of the tip.

We are using the proven probe in this thread

> Thanks to @Sunderlandkyl we managed to get our camera working. We now would like to replace the generic needle model with the actual optitrack probe/stylus model. Is there a repository of 3D models? For reference , this is what we have. [OptiTrack - Measurement Tools](https://www.optitrack.com/accessories/measurement-tools/)
