Hey IPA,
sorry for the late reply!
As the connectors on shop vacs are usually proprietary, you would need to 3D-print an adapter, at least for the last adapter that directly goes into the shop vacuum cleaner.
I saw the setup of Ed @cymro99 who connects a hose from Oneida to a Kärcher NT 40/1 TACT TE HEPA. I don’t know if there exists an adapter that Ed used to attach the hose to the vac, or if an adapter needed to be 3D-printed.
I think as long as I have not bought the Felder AF 22 that I intend to install in my planned new workshop when I will be able to move, I could try to connect my Festool CLEANTEC CTM MIDI I to a 70 mm hose with a 3D-printed adapter that I think I will design myself based on the festool hose connectors, or maybe there is such a 3D file already available somewhere
