About this 3D model

I have printed the cone part but have been unsuccessful with the large center part due to warping Not sure if the hose fittings are right yet., Uploaded for tips and maybe some tweaking for others to use. This should mate up to the contractors 1.5" hose. Not really sure if the baffle I put in there will help or hurt it's performance either. I have been printing with ABS and might try T-glase for the large top pieces.
