Gently tap it with a wooden hammer to achieve a snug fit. I used PLA for printing instead of ABS because the latter tends to deform. I've uploaded my parts and their positions for your reference. I increased the infill percentage of the handle - 15% was too low. I already broke one, so I reprinted it with a 45% infill rate. Please don't install it in the wrong direction, as it'll be hard to remove after installation. Also, disable the "Flow Calibration" during printing, as it can affect the quality of the printed parts.
If you plan to place it on top of the printer, don't print it first. I'm designing it to be placed on the printer, testing it and uploading it. My original design was for it to be placed on a table. If it's placed on the printer, it will interfere with the screen and the cover handle.

This version is an early design. I suggest printing the following version instead.

On the printer
