So the hose that comes with the Dyson pet grooming kit uses the v6 attachment system, they give you an adapter to plug it into v8 and newer vacuums such as the v15, but no adapter is present to plug a v8 or later accessory into the hose.

This model solves this exact problem.

Print as seen in the photo. i added support enforcers to sustain the v6 locking feature.
