This is a Holley Sniper EFI dash mount for a round vent Suzuki Samurai 1986 to 1988.5 I believe. I have a 1988 so that it was I designed with. This snaps into place in one of the dash vents. You will need to remove the air flow director in the vent you wish to use.

I printed this in Priline PC-CF and while not perfect the imperfections in the overhang do not affect the operation and are not visible when installed. I've enabled remixes in case others want to tweak settings and upload alternates.
