Eureka Vacuum SpaceBag Adapter

This is a vacuum adapter for using a Eureka EasyClean handheld portable vacuum (Model 72, Type A) to evacuate Space Bags.

The outside diameter of the vacuum hose end is ~ 31 mm.  I suspect that this adapter will fit other makes and models of smaller size vacuums.

I printed this with TPU because that's what was mounted in the printer but would expect any of the common filament materials to work equally well.

This piece was printed with a 0.4 mm nozzle, 0.2 mm layers, 0.8 mm walls, 16% infill, no supports, with the big end on the bed.  The internal shoulder is a bit ugly but it isn't near anything and didn't affect the functionality of the part.

The bottom edge is narrow and is chamfered on inside and outside diameters making contct area quite small.  It may be necessary to use a brim for adhesion.
