Fiat Qubo (Fiorino) Ventilation Grill Cover replacement for RAM mount 1" ball (Phone holder)

I made a simple cover/replacement for the ventilation duct to get a 1" RAM mount arm (b ball) connected. Just disassemble the orginial cover and stick in the printed part. Fits nice and strongly. 

arm from RAM mount → 793442004070

magsafe adapter RAM mount → 793442015236

I used PETG and printed the ball with 100% infill and the “base” with 35% Infill.
