This is an adapter for aftermarket speaker for use in 2004 Infiniti G35 front door speaker stock location without drilling new holes (you can use stock screws in original locations). I designed this adapter with 6.5" JBL speakers, but I'm sure you probably can use with other speaker brands. I used nut holes made to fit M4 nuts and M4x20mm bolts. Printed with nut hole side up and Cura default supports and brim.
