I purchased a replacement brush bar for my Dyson V7, only to find that the new brush bar uses a different mechanism to interface with the motor. (See photo comparing the two styles) I tried looking for the correct brush bar but as far as I can tell, Dyson changed the design a few years back and the older 3 Prong style brush bars are no longer available from the OEM nor 3rd party suppliers. Thankfully there is just enough room between the 4-Prong brush bar and the 3-Prong motor to fit this 3d printed adapter. This item might be a different colour depending on the filament I have. This sale is only for the adapter and nothing else.
