I tried sweeping but one opening is larger than the other and the sweep wont cover that. I can create one part fine using angled planes and lofts without minimize curves. I need to put two of them together. I cant loft two different parts to the same end point like I can with sweep. I tried booleans but that only seems to cut away a small amount. Im trying remove face but that makes the part not able to export to stl. You can see the rear port is flow through but the forward port will obstruct it when I combine the two.
