About this 3D model

This is a spacer for centering two nested, galvanized steel pipes. (Sized Ø1-¼" & 1" Sch 30 diameter). It printed fine out of Generic PC. I add a brim to the profile, but it also printed fine without it. Actual use was on a floating dock. The taper allows the retaining backet to pass by the outer pipe when the water level receeds.
