This 3D-printable speaker adapter was designed to fit aftermarket speakers in a 2012 Vauxhall/Opel Vivaro (Vivaro A) camper conversion. I created it for a family member after being unable to source a suitable adapter in time for a planned audio upgrade.
The design is based on the original factory speaker mounting and references other adapters I had from Connects2. It was printed in ABS for durability.
This adapter should also be compatible with the Renault Trafic and Nissan Primastar of the same generation, as these vans share similar components. However, compatibility with the second-generation Vivaro (Vivaro B), Trafic III, or NV300 has not been confirmed.
