NA Mazda MX-5 Miata Tweeter Bracket

thingiverse

For NA ('90-97) Mazda MX-5 Miatas (Miatae?) equipped with factory tweeters in the upper door panel. The factory tweeter is embedded in its plastic bracket that secures it to the panel and the back of the silver-trimmed grille, and is impossible to remove. I wanted to install new component speakers in the doors, including new tweeters, while retaining the original appearance. These brackets allow for this - the tweeters snap into place in the bracket and the bracket attaches to the original grille and subsequently the door panel just like the originals. Note: I designed these around the tweeters included with the Infinity PR6500CS speakers. Other tweeters may fit, but I have no way of knowing which they might be. The Infinity tweeters in question measure just over 32mm in diameter and just under 12mm in thickness, excluding the dome. Recommendation would probably be to print in ABS and do a light acetone treatment to ensure the best possible durability. Update 28 Nov 2018: V5 adds thickness and fillets to some areas to improve durability and prevent breakage. Print Settings Printer: Flashforge Creator Pro Rafts: No Supports: Yes Resolution: .150mm Infill: 25% Notes: Print with the flat side down. Fusion 360 seems to like exporting the STL in this orientation rather than how it's designed. Go figure. Support is required for the two tabs with large overhangs, but other areas should be fine without.
