Puxing 888k #-button cover

On some Puxing radios, hitting the #-button, even with the keypad locked, puts the radio into a different transmission mode without noticing the user other than changing frequency on the display. As such you loose contact with the people you intend to speak with. This can easily happen if you have the radio in a pouch. The cover blocks access to the #-button, while keeping all others available.

It clicks into place over the keypad. It is not connected very firmly.

Have uploaded the source file to FreeCAD, should anyone want to improve upon it.
