Panasonic Q GameCube DVD drive tray and rails.
These are replacements for your broken Q parts that always fail on these systems.
Replacing these and repairing the system isn't an easy feat, so please get a professional to do so unless you are confident in doing so yourself to avoid issues.
Screw holes are self-tapping on the rails.
These are printed on a high-quality resin printer and use a tough resin. They are much higher quality and more accurate than the standard PLA cheaper parts sold elsewhere. I recommend that when you refurbish the insides of your drive, you also lubricate the gears, etc., and replace the band to keep everything working well.
You won't find higher quality parts than these.
I pre lubricate this with molykote plastic lubricant but I recommend adding more if needed
