In our house we have a smart heating system from Tado that uses this Internet Bridge. This device is notorious for its poor connection range, and the best place we found to cover our entire house was on top of the storage rack we have in our utility room.
So I needed to model a suitable mount. It was a lot of measuring but after a few versions it fit perfectly. At the same time, because there is a microUSB connector used for power, which I don't like because of its easy damage. I made the side wall with the holes for the connectors thicker so it also works as a support for the cables. The model is simple to print and should fit all common storage racks.
EDIT 24.3.2023: I just added a version that has holes for 3,5mm countersunk head screws that were lying around in my workshop. And I also made a version for those who would like to use double sided tape.
Enjoy. :)
