Porsche seatbelt mounting support

This is a mounting support for an early Porsche 911/912 (1965-1972) non-automatic seatbelt. The original Porsche-part is out of stock and no longer available from Porsche.

V2: slightly wider holes for use with wider screws. Added Sketchup sourcefile.

Important: Use ABS because PLA will melt in the car!
