This is a remix of LizzyDesign's
Cyclone dust separator / vortex filter
32mm spiral tube Blast Gate.
I only modified the insert part of the Cyclone.
I wanted to connect my 32mm spiral hose to the cyclone without adaptor, so I added an internal thread to the original insert. I cut off the part after the external thread and replaced it with the internal thread part of the blast gate and added a linking segment. I also turned the outside of the hose side to a fully round one for smoother printing.
I'm a total beginner in terms of CAD and 3D printing so it may seem a bit unrefined ;)
