is is a sturdy right-angle pipe/ducting adapter designed specifically to mount directly into a standard 2×4 stud. Perfect for shop ventilation, fume extraction, or routing 4" dust-collection hose in tight spaces where a clean 90° turn is needed.
I designed this in Fusion 360 and printed the final part in PETG for durability and heat resistance. The fit is tight, strong, and ready for real workshop use.
