This is exactly how not to do it! The hole has only one purpose and that is for you to be able to mount the threaded screw on to the coupler.
When the build is complete the top of the threaded screw must just be under the hole (about 1mm) so it can move freely. It is very important that the threaded screw not touch any parts of the acrylic frame! The top of the thread screw may wobble which has absolutely no influence on print quality.
