Unfortunately, we do not have any 3D models of those products at this time, and I do not think anyone has worked on it. I was not able to find the question you were referring to. Could you post a link to it?
We still do not have the 3D model for the 3pi or m3pi. We are currently working on getting 3D models of our products on the website, but we do not have a timetable for when we will have model for those products. Is there something in particular you want to use the models for?
