This quality replacement has been CAD-modeled from scratch as opposed to 3D scanning and is manufactured using a custom blend of industrial grade resin plastic.

Replacing this part is an intermediate to advanced repair. I’ve taken the time to make a comprehensive replacement video to help minimize the odds of damaging the player while attempting the repair:

Please note that replacing the m-holder may or may not restore your player to full functionality. Especially if the original m-holder has been damaged due to shock or poor lubrication, other aspects of your player may need servicing or calibration to restore it to full working order. If your m-holder is physically broken, this replacement part will definitely take care of that aspect of your player's issues. If you are having problems beyond the mechanical failure of the m-holder, please consult an electronics repair technician in your area.
