This mount fits the Trail Tech 742-A00 Tach/Hr meter to the Offgrid Aviation throttle. The mount registers with the strain relief indentations to prevent rotation and is held on by two small zip ties. The tach is held onto the mount by two small zip ties.

Pictured is on left hand throttle. Its kind of upside down when viewing, but in the air with a little twist of the head and its perfectly readable. Right throttle would be perfect but who does that?

I have another version that mounts the tach in the opposite orientation, but the cord from the tach exits towards your hand instead of towards the engine. This 2nd version is easier to read orientation, but the cord exiting the wrong way is annoying. The 2nd version does have a passage to route the cord through and help tame the mess though.

I also created a third version that has raised lip around the perimeter of the tach, but printing requires supports and after testing I found the lip to be unnecessary, so I never printed it.
