Model originally uploaded to Thingiverse at https://www.thingiverse.com/thing:5185636.
I created these mounts to fit 6.5in Focal access 165AS speakers in a Volkswagen Pointer/Volkswagen Gol G3. (same car, different name depending on the country)
Original speakers were 5.25in, but there is almost perfect space for a 6.5in. Only had to sand down a little bit of the door panel to avoid the speaker surround from hitting it.
It is designed and tested for the 4-door version of the car. I do not know if the 2-door version will work.
It is not a perfect fit given the geometry of the door, but it is close enough to make it “plug-and-play” (I would say around 95% perfect fit)
Printed with Hatchbox ABS on a Prusa MK3S with Enclosure (IKEA Lack V1)
I recommend printing with the flat, speaker-side facing to the bed, and using supports for the mounting "ears".
USE THE INCLUDED GCODE FILES AT YOUR OWN RISK
On the gcode files used and attached here, I increased the temperature of the nozzle to 265ºC for the first layer and 280ºC for the rest, to decrease warping. (These are my personal standard settings for printing with hatch box ABS.) The print came out with no warping. It is also sliced at 100.33% scale to compensate for ABS shrinking (not really necessary since it isn't a detail-heavy print, simply part of my personal settings for ABS) I used a 30% infill (gyroid) for the main body and a 50% infill on the 3 mounting points (not completely necessary, just did it for extra strength since the speakers I used are a bit on the heavy side.
I SUGGEST SLICING YOUR OWN FILE FROM THE STLs IF YOU'RE USING ANOTHER BRAND OF ABS, WITH ITS CORRESPONDING SETTINGS
