spray can rack various diameter

I have now found some time and was able to expand the holder. Now there are different sizes in one ZIP. Not only the diameter of the spray can holder differs, but also the angle of the wall mounting. There should be a suitable angle for every diameter. There is also a spacer for mounting the bracket. The number of holes should be feasible with the standard print bed sizes.

The holder works without screws, it is simply plugged in
Otherwise, please give me constructive feedback.
