3x4 Downspout A/B Elbow to 4" Drain Tile Adapter

I've had some 4" drain tile that kept coming off my downspout elbow so I designed an adapter that slips on farther and has a snug fit. It's at a slight angle for downhill drainage, and the inside is rounded to funnel debris and water out. White is original

I redesigned it to look cleaner (Orange), print faster, and use less filament.
