Fartmaster 3000 (fm/3)

No matter how you get here, but right now you need to release the dragon and there are some people you love around. Turn on your noisy shop vac, as you do 1000 times a day, turn the gate on the device to ‘to-receiver’ direction, move your bum closer to the receiver, make a casual posture like nothing strange happens, do what you must. Nobody will hear you, nobody will smell you. You are stinky little ninja… Don't forget to switch to ‘pass-through’ direction again.

Device supposed to be placed anywhere you need as well as be hanged on an mft. To attach it to your vacuum, you can use adapter provided in FreeCAD project, but keep in mind that it is parametric and by default suits some theoretical 32mm tube. You can change this diameter to whatever suits you.

Please note that models are untested yet(I didn't have time and mft yet) and consider them as design ideas. All parts are parametric, feel free to use uploaded FreeCAD project to change parameters and analyze how the thing works.

Also, assembly TopCap - TopCapInsert - Gate supposed to be glued together.

Also, models saved in FreeCAD project lack any chamfers/fillets to be nice to touch. Because I found them quite conflict-prone with parametric parts. You can add them after you adjust parts for you needs.
