Dash ring mount for cigarette lighter socket. Probably works on other Mazdas as well, and maybe even other brands. When I was modelling this and looking for example pictures, it looks like they were made in both green for the Miatas and Orange. This was modeled for a '99 Miata. Although I didn't publish a picture, I printed it in ABS and it does work.
Used a brim rather than a raft in Cura. Should be able to print right side up or upside down.
Modeled with FreeCad 0.16
