Buy a step down ring, one that has a lip on the back and your filter thread size on the front. screw and glue that to the perspex permanently then you can just screw/unscrew your lenses as needed.
You could have done away with the cutouts and just used some of the existing screws to go through the acrylic as a permanent mount. Maybe. If they were long enough
