4 inch schedule40 pvc to 4 inch dust collection coupler
thingiverse
This is a male-male coupler, designed to fit inside a schedule 40 4" pvc pipe and connect to the inside of the larger diameter 4" dust collector fitting. The blast gate in the picture is from Woodcraft. Note this will not fit in the smaller dust collector side, only the larger side, so you can connect a hose to the smaller side. You may want to scale the z axis doen a bunch and print at 10% infil as a test to your pipes before printing the full size. On my elegoo neptune 3 pro, running at 30% infil and .28mm quality it took about 4.5 hours to print. I used supports to help with the middle part. The PVC side is a light fit, one layer of blue painters tape made it snug. This is my first design so please remix if you have improvements.
