The prompt

I would like to create a circular aluminum device that will be used to remove retainers used to hold down a glass lens. Some of these lenses are protruding above the retainer, so a concave bottom will be necessary in order to avoid scratching a lens. Also, in order to gain more torque in order to remove the retainer. The tool should have 2 through holes spaced 90 degrees from each other ( 4 holes that allow someone to push an allen key through) This tool should have 4 evenly spaced 1.25mm wide protrusions in order to fit within the retainers recessess.
