6 x 4 x 4-inch Dust Collection Wye for Flex Hose

Like a lot of woodworkers, I'm using PVC plumbing pipe in a central dust collection system in my shop. One drawback for this type of pipe is that the fittings are not designed for upwards of 1000 CFM air flow, and will introduce significant pressure drop to the system. Additionally, once you get up into 6 inch and bigger sizes, the fittings get expensive. These factors led to designing and printing my own fittings for the DC system. Blast gates, elbows, and wyes. I tried to design these to minimize pressure drop, and to fit the PVC sewer & drain pipe directly, without additional adapter fittings. The fewer fittings, the better for DC performance. This Wye fitting is similar to another 6x4x4 wye I uploaded, but instead of being all hubs, this one has a hub fitting at the 6" end, and the 4" branches are designed to fit 4" flex hose. Sorry, I don't have much info on print settings, it has been a while since I made one.
