NA Mazda Miata 3.5" Headrest Speaker Adapters

These were built for Kicker 46CSC354 3.5" speakers and should work for similar 3.5" speakers as well. Bolts that screw into the seat are 5mm-0.8 x 40mm long from Menards/Fastenal/Ace Hardware (could probably use ones 35mm long, but they didn't have enough where i bought mine). Then the screws mounting the speaker to the adapter are from Walmart (#6x1/2") I would recommend using the “strength” preset in Bambu Studio or change your wall thickness for the speaker screw holes cause they cut through the plastic to make the threads. (Shown in last picture) I also printed these out of PETG for increased durability but probably not required. (The red adapters in the picture are made from PLA+ as a test piece, took 3 adaptations to get it perfect)
