Good morning! I was informed that the 6R seems to have a hole in the middle of the model so I am going back over all of them to double check and fix. If you are having no problems with printing, awesome! But if you are, I am getting this worked out.
I have no idea why this model is giving me such problems converting to STL when I have made it the same way I do every other model. Must be because my printer is on the way.
