Shop vac hose inlet to 4 inch ID Dust Collection hose or 100mm OD Straight Pipe

Background

I bought an old version of a Dust Right(r) 4 inch quick disconnect.  For my purposes, it has been best to use it backwards (inlet as outlet).  I printed an adapter for a 4 inch flex hose to hook to what is normally the quick disconnect end (normally the inlet).  I have been printing adapters for various tools to attach to the to what is supposed to be the outlet for a 4 inch flex hose (so normally the outlet).  (see picture)

In order to make this more generically connection useful I have added the 4 inch Hose ID to 100 mm OD hard adapter.  Full disclosure, I have not printed this adapter because I don't currently need it.  If it needs tweaked send me a comment.

Details

This adapts a normal shop vac hose inlet to a 100 mm OD pipe.  The 100 mm side has a short 103 to 100 mm taper to ease pipe insertion.  I print this flat side down with flex (95A TPU) flat side down.

The 4 inch Hose ID to 100 mm OD should be printed rigid, PLA, PETG et al.  Hose clamp may be needed on the 4 inch end.  Everything else should be friction fit.
