Sprite Pro Ring Duct "Fixed" Optimized Supports

I've seen some comments about the issues of the provided supports and I was requested to post up my file that I've had success with. This orientation and support placement has always ended successfully on my Mars Pro with the smallest layer line settings possible .02 I believe. The thing wall is still an issue with this model, all this provides for is supports placement that works for me. This does NOT mean it will work for you. It's a .ctb file.

I will remix the remixes with “better” walls shortly.
