Center speaker dash mount

I printed this out of PTEG at 50 percent fill and it seems fine. Because it's shaped to fit the contour of the dash (early Vanagons with the center speaker and no dash pad), supports are needed on the build plate. I used a Ram mount 1" ball with the M10x1.25 thread, along with a Blue Sea Systems receptacle. M5 nutserts are used in the dash with the speaker section cutout.
