BMW E30 Premium Rear Tweeter Hertz DT 24.3 Countersunk Mount Plate

These are included in the Hertz DSK 130.3 component speaker set. The center hole is 36mm which may fit other tweeters. These fit below the original BMW perforated cover/grill. I designed them so that no supports are required when printing. I used ASA filament to withstand the temperatures that the cabin may get not to mention the fact that these will be in direct sunlight. I recommend that you adjust your slicer so that the first layer speed be 8 mm/s. In Prusaslicer this is found under Print Settings, Modifiers, First Layer Speed.
