I designed this compressor tool for the University of Miami's Internal Combustion Engines Laboratory to help make flow bench analysis easier. Typically running the flow bench requires two people, one to hold the micrometer down to keep the valves open, and one to operate the flow bench. This rig eliminates the need for a second person by bolting directly to the cylinder head. It is also fully adjustable with 3 degrees of freedom that allow it to be used on multiple different cylinder heads. It was printed on an Elegoo Mars 5 Ultra resin printer. It is fully functional and currently being used by students learning the flow bench.
