Cupholder for people without wrist rotation

Lack of mobility in the wrist was what motivated me to create this glass adapter. Because of this lack mobility I can not pick up the glass as " normal people " . With this adapter , I can plug into a common cup and drink the liquid without the help of straws , since as the adapter is designed in two parts , you can change the angle of the adapter as it is used , it fits perfectly in the mouth.
