This is a remix of Alaorath's design that holdes dyson v6 accessories.
I have made the hole larger so it is easier to insert the accessories, also added a notched version that can accept powered accessories that have the power pin at the back.
Comes with elevated wall mount that should be able to hold most accessories without the accessory touching the wall.
You will need a small spring to fit behind the button to make the button work correctly.
Something like this should work:
