sliced the insert and body as two files but aligned them on the print bed in cura so I could print the insert, then do a filament change, then print the body. Tried another filament swap halfway through but that didn't work too well. Live and learn. Also printed with 0 top and bottom layers to get a lattice effect but the part isn't really thick enough for it to show well.

Put a length of 1/2" PVC pipe between the two stands are you are good to go.
