About this 3D model

The piggy back tuner on my brothers car has a serial connection on the device and an open USB male connector on the other end, which just sits in the engine compartment. I tried it on an Apple USB end, but it's so slick it does not stay on as well. I also printed one for my Replicator USB cable which I always leave connected, if a file or xacto knife were to short the cable it would blow the Mightyboard.
