Owner notes
BY SUBMATIXSMS100

Multipart spacer set for installing a 6.5-inch front-door speaker without modifying the door. Print one base plate and two copies of the spacer, as the creator specifies. Explicitly designed for Alfa Romeo 147 and 156 doors. PETG is inferred for cabin heat resistance and screw-clamping toughness; ABS is an alternative.
