4" to Dual 2.5" Dust collector splitter

thingiverse

This adapter connects a 4-inch dust collector to two 2.5-inch ports, minimizing pressure head loss by preserving suction power from the 4-inch collector. The adapter's outlets are positioned at a 30-degree angle relative to the 4-inch inlet, providing a seamless transition inside. To optimize performance, I designed this adapter with an inward thickness of 0.1 inch, slightly exceeding standard sidewall dimensions of 0.08 inch. For printing, ensure the 4-inch side is facing the printer bed.
