Summary

This adapter is made for that terrible day when your washing machine breaks mid-wash still with the main part full of water. By partially disassembling the washer (taking off the outer cover, and taking the pump off of the motor), you can get access to the pump. This adapter fits with one end (the hexagonal end) in a regular cordless or corded drill with a chuck and the other end into the pump. Running the drill thus connected to the pump will pump the water out of the washer down the drain pipe your washer is already connected to.

This adapter specifically works with a Kenmore 70 Series washing machine pump, but probably fits other models, though it's not tested with any other models.

Also note that even at 100% infill, this part is not really strong enough to take the strain and will break, but I was able to drain the full tank only breaking three. So print backups, but you probably won't need many more than a handful.

The part where it breaks is always right at the junction where the hexagonal part that goes into the drill meets the part that goes into the pump. So the strength/durability of the part might be possible to improve by making a smoother transition at that point. But this being a quick and dirty solution to a quick and dirty problem, I haven't gone to the trouble of working to improve the model any. Also, the OpenSCAD file could be improved with a couple of linear_extrudes.
