This was designed specifically for the accessories that come with the Ryobi cordless vacuum, but it may work for similar vacuum accessories where the outer diameter of the pipe/accessory is 32mm. Otherwise it could be scaled up or down for the appropriate sizing.
This isn't a symmetrical model as the spacing was designed to fit the Ryobi accessories fairly precisely.
Also comes with a wall hook for storing the longer straight pipe.
The author marked this model as their own original creation.
