This simple wall mount was intended to be universal, except that every vacuum brand it seems has a different diameter fitting!
The model attached has a 34mm diameter spigot for the accessory and there is 30mm clearance from the wall.
It shouldn't be terribly difficult to scale it in the slicer to suit your exact model. Scale only the X and Y dimensions and leave the Z as is.
It is a single mount to allow flexibility in size, heights and numbers of brushes. This one was made for a friend who intends to mount five on a varnished board in his broom cupboard.
The author marked this model as their own original creation.
