I require assitance regarding how to find the drawings and proportions for the door to the usb bay of the Razer Lancehead Wireless Mouse.

Since my door needed for holding the wireless usb connector is broken i am unable to safely store the usb.. :C
I would greaty  appreciate if someone could deliver the drawings or (if there is one) a 3d model for this part of the mouse so that im able to 3d print a new one.
