Physical dimensions of Nitrokey 3C NFC

Hi,
What are the physical dimensions of the Nitrokey 3C NFC? I’m most interested in the total width (perpendicular to the direction the USB port is inserted), and the clearance required on either side of the USB port.
Thanks

Hello, the Nitrokey 3C NFC is about 4cm long with the USB port and 1.9cm wide.
