30:1 Premix Measure

This is a measuring cup for 2 stroke premix oil. It is designed for a 30:1 ratio with 1 gallon of gasoline. The line inside the measure is 4.5 ounces. As some oil sticks to the side it should give pretty close to 4.3 ounces when poured in. I did test this with a calibrated measuring cup. I printed mine with clear PETG on an Ender 3 and it was water tight. This was specifically designed to use with the DLE 35RA that is in my Hangar 9 RV4. No supports, raft, or brim needed.
