Olive Submersion Tool

Short sad story: I harvest olives from one of the trees in my garden and watch tutorials on how to prepare them. In the videos they show a plastic tool similar to this one to keep the olives submerged in water and prevent them from getting moldy. 5 minutes of modeling and I solved the problem, I hope it can be useful to others.
The model can be scaled to work with various jar and bottle designs. In my case the diameter is 65 millimeters and the height 22.5 millimeters.
