This is a ball mount that can be put in between two trim pieces on an SEAT Alhambra or VW Sharan to attach an ESR MagSafe charger. You just need to carefully force it in right above the aircon unit, either on the right or left. I recommend printing in PETG or PETG-CF for temperature reasons.
For enhanced stability I recommend putting a small double sided sticky tape underneath. It will however also work without one.
