Hi @Anonymous,

I took a look at your file. In order to get it to a 3D printer I wanted to export the data to SAT  (ACIS format) or STL (Lithography)

I tried exporting the model but it indicated that it was not watertight. So, I ran CONVTOSURFACE on the entire model and then exported to SAT format. The resulting file is nearly 700 MB's in size.

This is only the first step as there is no guarantee that it is clean enough to print. I have not done any kind of 3D printing from the Mac side so I apologize if my information is incomplete.

I am taking the SAT file into Fusion 360 next. This will take a while and I will post back with the results.
