A freely sizeble rack/holder for ultrasonic cleaners (You can just enter the dimensions and the model should scale automatically in all dimensions.) Created for holding a smaller solvent container inside the ultrasonic bath chamber such that the smaller container does not float and tip over. (Filling just a small cup with the solvent reduces the use of it.) Filling the container with water mediates ultrasonic sound. You can also use the rack to hold directly the items you are washing but then choose a material can stand the solvent you are using.
