This is another part of my dust collection system I use in my workshop aka SShopDC. This are connectors for 50 +/-2mm (depends where you buy) elastic hoses to connect them to 50mm pipes and/or my other parts like iris valve (blast gate).
On picture you can see:
- This is just standard 50mm pipe with hose put on it - you can wrap it with tape and call it done
- This is printed sleeve on 50mm pipe to hold the hose - there is a matching screw (to the one on hose) inside
- This is hose end (not requiring pipe) dedicated for connection with other pipe components
- Finally, this one is also hose end, but dedicated for my iris valve
All connectors will fit to my iris blast gate, simply 4th one is designed just for this purpose. So if you want to be versatile, go with 2 or 3. If you want only to use it with iris valve - go with 4.
Like you can also see on the picture, steel core hose is twisted clockwise and brass one anticlockwise. That's why I have two sets of models CW and ACW. Also steel one is slightly bigger (about 54mm) - so there is also version with B letter - as Bigger.
Of course in your case brass can be CW or ACW - just check it.

No support needed, infill does not really matter - just make sure you have at least 2 perimeters (I print with 3).
When printing with 0,25mm it should fit all perimeters nicely - but it depends on your slicer.
Not needed, but you may want to sand rough spots if you have any.
