Shopvac ABS Adaptor

This coupling is designed to connect my shopvac end (1.785" OD) with some 1.5" ABS Pipe (1.91" OD) I plan on putting it on the outside of both pipes. Both ends are not tapered. The model is 1/8" thick and has a 1/8" transition taper in the middle. I sliced it in Cura, but drew it in Sketchup in inches. When I imported it into Cura, I had to change the milimeters on the Z axis to 57.15 (scaling it).

I'm printing at 100% infill, Brim, PLA (215/60).
