This is a Hose adaptor for a 1.25 inch shop vac to a Kreg router table dust collection port.
If you're thinking about potentially using it for something else the important dimensions are as follows...
outer diameter large hole 2.3 in
inner diameter large hole 2.1 in
outer diameter small hole 1.39 in
inner diameter small hole 1.24 in
Normal distance from top hole to bottom hole 3.13 in
Max diameter 2.69 in
Orientate so small hose fitting is on the bottom to avoid using supports.
Raft is just there to help ensure the starting layer sticks through the entire print. I reduced the raft margin to 2mm as I didn't think more would be necessary.
The fixed shell starting point setting disabled to avoid having one of those unsightly zippers down the part.
1Hr 45Min print time on my printer. No cleanup was required.
