Wall mount shelf that fits a cable modem "Sagemcom WiFi Hub C2 - F@ST 3890V3 CHWU"
The supports below the shelf doubles as convenient points to tie the cables to.
The hexagonal holes in the shelf are for ventilation, as the modem has intakes on the bottom. The areas that lack holes are where the rubber feet of the modem goes. Also the holes save (some) plastic.
Screw holes were placed like they were since I already had screwholes from a previous modem (that had built in mounting holes).
