To register your design within the EU, you should file an application with the European Union Intellectual Property Office (EUIPO). Protection is valid for a maximum of 25 years.
Even unregistered designs are given some protection under this regulation. As soon as a design that meets the requirements for protection is made public, it is given protection against imitations. However, this unregistered protection is only valid for three years from when the design was made public.

Almost everything is design, good or bad. And it can be design worth protecting. Design is often part of a business strategy. If you protect the design of your product, no competitor has the right to copy it. You reduce the risk of being pirated. You state that you are the original.
