Dual-sided 4" QuickConnect (Rockler-compatible) OD, with different tapers on the ID to fit various hoods and machines.

Store bought 4" dust collection fittings are ridiculously inconsistent in size. I have two very similar dust hoods with different ODs, and I made this adaptor primarily so I could use them both with my Rockler DustRight “QuickConnect” hose.
The outer diameter (OD) on both sides fits the Rockler hose/handle, and the inner diameter (ID) has differ tapers on each side to fit a variety of machines and other 4" fittings like the hood pictured.
PETG recommended over PLA for strength and flexibility.
Tip: I made this a bit longer than needed, so I could mount it to a ball-joint tripod near my lathe. So unless you need that length, save yourself from plastic and print time by scaling the height disproportionately.
Let me know how you adapt it to your own needs.
