This bracket is for keeping the Digipass 831 security token from Postfinance at his assigned position. Always when I had to make some internet banking I searched my Digipass device from Postfinance. So i decided to to assign a fixe place where i store the Digipass. Because i already have many things on my desk t designed this brackte to store the Digipass underneath the desk surface. https://youtu.be/59sWRMnXL_k This Bracket is designed for a Digipass with the measuring of 62mm with, 12mm height and approximately 90mm lenght. If you need some other dimensions, I can generate a *.stl for you. Generally it is a general purpose bracket. It can also be mounted on a wall, either for putting the device in from above, or from the side. Mounted upstanding on the wall you can use your Digipass without removing it out of the bracket.
